Norwegian Americans ( Bokmål: Norskamerikanere, Nynorsk: Norskamerikanarar) are Americans with ancestral roots from Norway. Norwegian immigrants went to the United States primarily in the later half of the 19th century and the first few decades of the 20th century. There are more than 4.5 million Norwegian Americans, according to the most recent U.S. census,[ specify]; most live in the Upper Midwest. Norwegian Americans are currently the 10th-largest European ancestry group in the United States.

Norsemen from Greenland and Iceland were the first Europeans to reach North America. Leif Erikson reached North America via Norse settlements in Greenland around the year 1000. Norse settlers from Greenland founded the settlement of L'Anse aux Meadows and Point Rosee in Vinland, in what is now Newfoundland, Canada.  These settlers failed to establish a permanent settlement because of conflicts with indigenous people and within the Norse community.
There was a Norwegian presence in New Amsterdam (New York after 1664) in the early part of the 17th century. Hans Hansen Bergen, a native of Bergen, Norway, was one of the earliest settlers of the Dutch colony of New Amsterdam having immigrated in 1633.
Another of the first Norwegian settlers was Albert Andriessen Bradt who arrived in New Amsterdam in 1637. Pieter Van Brugh, Mayor of Albany, New York was the grandson of Norwegian immigrants. His mother's parents were Roelof Janse (1602–1637), born in Marstrandsön, a small island situated in Båhuslen province in Norway (it was ceded to Sweden in 1658) and Anneke Jans (1605–1663), born on Flekkerøy, an island situated outside the town of Kristiansand, Vest-Agder county, Norway. 
Approximately 60 people had settled in the Manhattan area before the British take-over in 1664. How many Norwegians that settled in New Netherland (the area up the Hudson River to Fort Oranje—now Albany) is not known. The Netherlands (and especially Amsterdam and Hoorn) had strong commercial ties with the coastal lumber trade of Norway during the 17th century and many Norwegians immigrated to Amsterdam. Some of them settled in Dutch colonies, although never in large numbers. (For further reading, see for example J.H. Innes, New Amsterdam and its people.) There were also Norwegian settlers in Pennsylvania in the first half of the 18th century, upstate New York in the latter half of the same century, and in New England during both halves. 
The earliest immigrants from Norway to America emigrated mostly because of religious motives, as Religious Society of Friends and Haugeans. Organized Norwegian immigration to North America began in 1825, when several dozen Norwegians left Stavanger bound for North America on the sloop Restauration (often called the "Norwegian Mayflower) under the leadership of Cleng Peerson. To a great extent, this early emigration from Norway was born out of religious persecution, especially for Quakers and a local religious group, the Haugianerne. 
The ship landed in New York City, where it was at first impounded for exceeding its passenger limit. After intervention from President John Quincy Adams, the passengers moved on to settle in Kendall, New York with the help of Andreas Stangeland, witnessing the opening of the Erie Canal en route. Many of these immigrants moved on from the Kendall Settlement, settling in Illinois and Wisconsin. Cleng Peerson became a traveling emissary for Norwegian immigrants and died in a Norwegian Settlement near Cranfills Gap, Texas in 1865. 
...in 1825, during a period of particularly fierce religious strife in Norway. In July of that year, a group of six dissenting families, seeking a haven from the official Norwegian state church, set sail from Stavanger in an undersized sloop, the Restaurationen. When it arrived in New York harbor after an arduous 14-week journey, the Restaurationen caused a sensation, and the local press marveled at the bravery of these Norwegian pilgrims. Local Quakers helped the destitute emigrants, who eventually established a community in upstate New York. Today, their descendants are still known as 'sloopers'." 
While about 65 Norwegians emigrated via Sweden and elsewhere in the intervening years, no emigrant ships left Norway for the New World until the 1836 departures of the Den Norske Klippe and Norden. In 1837, a group of immigrants from Tinn emigrated via Gothenburg to the Fox River Settlement, near present-day Sheridan, Illinois. But it was the writings of Ole Rynning (1809–1838), who traveled to the U.S. on the Ægir in 1837 that energized Norwegian immigration.  
Throughout much of the latter part of the 19th century and into the 20th century, a vast majority of Norwegian emigration to both the United States and Canada followed a route commonly shared by most Swedish, Danish and Finnish emigrants of the period, being via England by means of the monopoly established by the leading shipping lines of Great Britain, primarily the White Star Line and the Cunard Line, both of which operated chiefly out of Liverpool, England.   These lines negotiated with smaller 'feeder lines', primarily the Wilson Line, which was based out of the port city of Hull on England's east coast, to provide emigrants with passage from port cities such as Christiania (Present-Day Oslo), Bergen and Trondheim to England via Hull.  Steamship companies such as Cunard and White Star included fares for passage on these feeder ship in their overall ticket prices, along with railway fares for passage between Hull and Liverpool and temporary accommodations in numerous hotels owned by the shipping lines in port cities such as Liverpool.  Most Norwegian emigrants bound for the United States entered the country through New York City, with smaller numbers coming through other eastern ports such as Boston and Philadelphia. Other shipping lines such as the Canadian Pacific Line,  which also operated chiefly out of Liverpool, and the Glasgow-based Anchor Line  operated routes to ports in eastern Canada, primarily Quebec City, Montreal and Halifax. Because Canadian-bound routes were slightly shorter, lines which disembarked at Canadian ports often provided quicker passages and cheaper fares.
The Canadian route offered many advantages to the emigrant over traveling to the USA directly. "They moved on from Quebec both by rail and by steamer for another thousand or more miles (1,600 km) for a steerage fare of slightly less than $9.00. Steamers from Quebec, Canada brought them to Toronto, Canada then the immigrants often traveled by rail for 93 miles to Collingwood, Ontario, Canada on Lake Huron, from where steamers transported them across Lake Michigan to Chicago, Milwaukee and Green Bay. Not until the start of the 20th century did Norwegians accept Canada as a land of the second chance. This was also true of the many American-Norwegians who moved to Canada seeking homesteads and new economic opportunities. By 1921 one-third of all Norwegians in Canada had been born in the U.S.
Norwegian immigration through the years was predominantly motivated by economic concerns. Compounded by crop failures, Norwegian agricultural resources were unable to keep up with population growth, and the Homestead Act promised fertile, flat land. As a result, settlement trended westward with each passing year.
Early Norwegian settlements were in Pennsylvania, Massachusetts, and Illinois, but moved westward into Wisconsin, Minnesota, and the Dakotas. Later waves of Norwegian immigration went to the Western states such as Washington and Oregon, and Utah through missionary efforts of gaining Norwegian and Swedish converts by the Mormons. Additionally, craftsmen also immigrated to a larger, more diverse market. Until recently, there was a Norwegian area in Sunset Park, Brooklyn originally populated by Norwegian craftsmen.
Between 1825 and 1925, more than 800,000 Norwegians immigrated to North America—about one-third of Norway's population with the majority immigrating to the US, and lesser numbers immigrating to the Dominion of Canada. With the exception of Ireland, no single country contributed a larger percentage of its population to the United States than Norway.  Data from the U. S. Office of Immigration statistics of the number of Norwegians obtaining lawful permanent resident status in the US from 1870 to 2016 highlights two peaks in the migration flow, the first one in the 1880s, and the second one in the first decade of the 20th Century. It also shows an abrupt decrease after 1929,  during the economic crisis of the 1930s.
During the colonial period, Norwegian immigrants often joined the Dutch seeking opportunities for trade and a new life in America. The Dutch often took Norwegians with them to the New World for their sailing expertise.  Many immigrants during the early 1800s sought religious freedom.
From the mid-1800s however, the main reasons for Norwegian immigration to America were agricultural disasters leading to poverty, from the European Potato Failure of the 1840s to Famine of 1866–68. The agricultural revolution also put farmers out of work and pushed them to seek employment in a more industrialized America. 
The majority of the pioneer immigrants, the so-called "Sloopers," assisted by the kindly services of American Quakers, went to Orleans County in western New York state and settled in what became Kendall Township. In the mid-1830s the Kendall settlers gave impetus to the westward movement of Norwegians by founding a settlement in the Fox River area of Illinois. A small urban colony of Norwegians had its genesis in Chicago at about the same time.
Immigrant settlements now stood ready to welcome Norwegian newcomers, who, beginning in 1836, arrived annually. From Illinois, Norwegian pioneers followed the general spread of population northwestward into Wisconsin. Wisconsin remained the center of Norwegian American activity up until the American Civil War, a war in which a number of Norwegian Americans fought for the Union, such as in the 15th Wisconsin Volunteer Regiment. In the 1850s Norwegian land seekers began moving into both Iowa and Minnesota, and serious migration to the Dakotas was underway by the 1870s.
The majority of Norwegian agrarian settlements developed in the northern region of the so-called Homestead Act Triangle between the Mississippi and the Missouri rivers. The upper Midwest became the home for most immigrants. In 1910 almost 80 percent of the one million or more Norwegian Americans—the immigrants and their children—lived in that part of the United States. In 1990, 51.7 percent of the Norwegian American population lived in the Midwest; Minnesota had the largest number. Minneapolis functioned as a Norwegian American "capital" for secular and religious activities.
In the Pacific Northwest, the Puget Sound region, and especially the city of Seattle, became another center of immigrant life. Enclaves of Norwegian immigrants emerged as well in greater Brooklyn, New York, in Alaska, and Texas. After Minnesota, Wisconsin had the most Norwegians in 1990, followed by California, Washington, and North Dakota.
A newcomer from Norway who arrives here will be surprised indeed to find in the heart of the country, more than a thousand miles from his landing place, a town where language and way of life so unmistakably remind him of his native land. Svein Nilsson, a Norwegian American journalist (in Billed-Magazin, May 14, 1870).
This sentiment was expressed frequently as the immigrants attempted to seek acceptance and negotiate entrance into the new society. In their segregated farming communities, Norwegians were spared direct prejudice and might indeed have been viewed as a welcome ingredient in a region's development. Still, a sense of inferiority was inherent in their position. The immigrants were occasionally referred to as "guests" in the United States and they were not immune to condescending and disparaging attitudes by old-stock Americans. Economic adaptation required a certain amount of interaction with a larger commercial environment, from working for an American farmer to doing business with the seed dealer, the banker, and the elevator operator. Products had to be grown and sold—all of which pulled Norwegian farmers into social contact with their American neighbors.
In places like Brooklyn, Chicago, Minneapolis, and Seattle, Norwegian-Americans interacted with the multi-cultural environment of the city while constructing a complex ethnic community that met the needs of its members. It might be said that a Scandinavian melting pot existed in the urban setting among Norwegians, Swedes, and Danes, evidenced in residential and occupational patterns, in political mobilization, and in public commemoration. Inter-marriage promoted inter-ethnic assimilation. There are no longer any Norwegian immigrant enclaves or neighborhoods in America's great cities. Beginning in the 1920s, Norwegian-Americans increasingly became suburban, and one might claim, more American. 
Norwegian Americans cultivated bonds with Norway, sending gifts home often and offering aid during natural disasters and other hardships in Norway. Relief in the form of collected funds was forthcoming without delay. Only during conflicts within the Union between Sweden and Norway, however, did Norwegian Americans become involved directly in the political life of Norway. In the 1880s they formed societies to assist Norwegian liberals, collecting money to assist rifle clubs in Norway should the political conflict between liberals and conservatives call for arms.
The ongoing tensions between Sweden and Norway and Norway's humiliating retreat in 1895 fueled nationalism and created anguish. Norwegian Americans raised money to strengthen Norway's military defenses. The unilateral declaration by Norway on June 7, 1905, to dissolve its union with Sweden yielded a new holiday of patriotic celebration.
In American popular culture, Norwegian Americans were the central characters in the popular CBS network television series, Mama (1949–1956). Set in San Francisco around 1900, the weekly program focused on working-class family life.  They also form the background to Garrison Keillor's " Lake Wobegon" series of novels.
According to a 2018 paper, Norwegian immigrants who lived in large ethnic enclaves in the United States in the 1910 and 1920 "had lower occupational earnings, were more likely to be in farming occupations, and were less likely to be in white-collar occupations." 
- There are more than 4.5 million people of Norwegian ancestry in the United States today. Of these, approximately three million claim "Norwegian" as their sole or primary ancestry. The population of Norway itself in 2013 was 5.1 million.
- A little more than 2% of whites in the United States are of Norwegian descent. In the Upper Midwest, especially Minnesota, western Wisconsin, northern Iowa, northern Illinois, and the Dakotas, more than 15% of whites are of Norwegian descent. Nearly one-third of all North Dakotans claim Norwegian as their ancestry.[ citation needed]
- 55% of Norwegian Americans live in the Midwest; 21% live in California, Oregon and Washington.
- Norwegian Americans actively celebrate and maintain their heritage in many ways. Much of it centers on the Lutheran-Evangelical churches they were born into. Culinary customs (e.g., lutefisk and lefse), national dress ( bunad), and Norwegian holidays ( Syttende Mai, May 17) are also popular. A number of towns in the United States, particularly in the Upper Midwest, display very strong Norwegian influences.

Use of the Norwegian language in the United States was at its peak between 1900 and World War I, then declined in the 1920s and 1930s. Over one million Americans spoke Norwegian as their primary language from 1900 to World War I, and more than 3,000 Lutheran churches in the Upper Midwest used Norwegian as their sole language. There were hundreds of Norwegian-language newspapers across the Upper Midwest:
- Decorah Posten and Skandinaven were major Norwegian language newspapers.
- The Northfield Independent was another notable newspaper. The editor was Andrew Rowberg, who collected massive numbers of Norwegian births and deaths in U.S. The file he created is now known as The Rowberg File Maintained at St. Olaf College, and is commonly used in family research across the US and Norway.
- Over 600,000 homes received at least one Norwegian newspaper in 1910.
However, use of the language declined in part due to the rise of nationalism among the American population during and after World War I. During this period, readership of Norwegian-language publications fell. Norwegian Lutheran churches began to hold their services in English, and the younger generation of Norwegian Americans was encouraged to speak English rather than Norwegian. When Norway itself was liberated from Nazi Germany in 1945, relatively few Norwegian Americans under the age of 40 still spoke Norwegian as their primary language (although many still understood the language). As such, they were not passing the language on to their children, the next generation of Norwegian Americans.
Some sources stated that today there are 81,000 Americans who speak Norwegian as their primary language, however, according to the US Census, only 55,475 Americans spoke Norwegian at home as of 2000, and the American Community Survey in 2005 showed that only 39,524 people use the language at home.  Still, most Norwegian Americans can speak a common Norwegian with easy words like hello, yes and no. Today, there are still 1,209 people who only understand Norwegian or who do not speak English well in the United States. In 2000 this figure was 215 for those under 17 years old, whereas it increased to 216 in 2005. For other age groups, the numbers went down. For those who are from 18 to 64 years old, went down from 915 in 2000 to 491 in 2005. For those who are older than 65 years it went drastically down from 890 to 502 in the same period.  The Norwegian language is likely to never die out in the U.S. because there is still immigration, of course on a much smaller scale, but they emigrate often to other areas, like Texas, where the number of Norwegian speakers increase.
Many Lutheran colleges that were established by immigrants and people of Norwegian background, such as Luther College in Decorah, Iowa, Pacific Lutheran University in Tacoma, Washington, and St. Olaf College in Northfield, Minnesota, continue to offer Norwegian majors in their undergraduate programs. Many major American universities, such as the University of Washington, University of Oregon, University of Wisconsin–Madison, and the Indiana University offer Norwegian as a language within their Germanic language studies programs.
Two Norwegian Lutheran churches in the United States continue to use Norwegian as a primary liturgical language, Mindekirken in Minneapolis and Minnekirken in Chicago. There are also several Norwegian Seaman's Churches in the US that have services in Norwegian. They are located in Houston, Los Angeles, San Francisco, Miami, New Orleans, and New York.
Literary writing in Norwegian in North America includes the works of Ole Edvart Rølvaag, whose best-known work Giants in the Earth ("I de dage", literally In Those Days) was published in both English and Norwegian versions. Rølvaag was a professor from 1906 to 1931 at St. Olaf College, where he was also head of the Norwegian studies department beginning in 1916.

Most Norwegian immigrants to the United States, particularly in the migration wave between the 1860s and early 20th century, were members of the Church of Norway, an evangelical Lutheran church established by the Constitution of Norway. As they settled in their new homeland and forged their own communities, however, Norwegian-American Lutherans diverged from the state church in many ways, forming synods and conferences that ultimately contributed to the present Lutheran establishment in the United States. 
The Norwegian Lutheran church was a focal point in rural settlements in the Upper Midwest. The congregation became an all-encompassing institution for its members, creating a tight social network that touched all aspects of immigrant life. The force of tradition in religious practice made the church a central institution in the urban environment as well. The severe reality of urban life increased the social role of the church.[ citation needed]
The Church of Norway largely ignored the immigrants and provided no guidance. As a consequence, no fewer than 14 Lutheran synods were founded by Norwegian immigrants between 1846 and 1900. In 1917 most of the factions reconciled doctrinal differences and organized the Norwegian Lutheran Church in America. It was one of the church bodies that in 1960 formed the American Lutheran Church, which in 1988 became a constituent part of the newly created Evangelical Lutheran Church in America. 
Most Norwegians have been Lutheran. There were Methodists concentrated especially in Chicago, with its own theological seminary. Some Norwegians became Baptists. There were also groups of Quakers, relating back to "the Sloopers," and Mormons who joined the trek to the "New Jerusalem" in Salt Lake City, Utah.

In entertainment, Sigrid Gurie, "the siren of the fjords," starred in numerous motion pictures in the 1930s and 1940s. Other Hollywood actors and personalities with one Norwegian parent or grandparent include James Arness, Paris Hilton, James Cagney, Peter Graves, Tippi Hedren, Lance Henriksen, Celeste Holm, Kristanna Loken, Robert Mitchum, Piper Perabo, Priscilla Presley, Michelle Williams, Rainn Wilson, and Renée Zellweger. Seminal protopunk musicians Iggy Pop of The Stooges and David Johansen of the New York Dolls and Don Dokken of the heavy metal band Dokken have Norwegian ancestry. Paul Waaktaar-Savoy of the synth pop band a-ha is Norwegian, having been born and raised in Oslo. He is a naturalized American citizen and has homes in both Oslo and New York City.
In journalism, Eric Sevareid, was a well-known a CBS reporter and commentator. In literature, Ole Edvart Rølvaag wrote about the immigrant experience, especially the Norwegian-American experience in The Dakotas. Rølvaag's home is a National Historic Landmark.
In labor unions, Andrew Furuseth was largely responsible for the passage of four reforms that changed the lives of American mariners. Two of them, the Maguire Act of 1895 and the White Act of 1898, ended corporal punishment and abolished imprisonment for deserting a vessel. The Seamen's Act of 1915 included all these and was his main project.
Minnesota Democratic Senators Hubert Humphrey and Walter Mondale served as the 38th and 42nd Vice Presidents of the United States, respectively, and were nominees for President in 1968 and 1984, respectively. Earl Warren of California was the 14th Chief Justice of the United States.
In science, Ernest Lawrence won the Nobel Prize in Physics in 1939.  Lars Onsager won the 1968 Nobel Prize in Chemistry. Norman Borlaug, father of the Green Revolution, won the Nobel Peace Prize in 1970. Christian B. Anfinsen won the Nobel Prize for chemistry in 1972. Ivar Giaever won the Nobel Prize in Physics 1973. Carl Richard Hagen is noted for his work in physics.
In engineering, Clayton Jacobson II is credited with the invention of the modern personal watercraft. Ole Singstad was a pioneer of underwater tunnels. Ole Evinrude invented the first outboard motor with practical commercial application, recognizable today on modern motorboats.
In religion, Olaf M. Norlie created the Simplified New Testament. Herman Amberg Preus was a key leader in the development of the Synod of the Norwegian Evangelical Lutheran Church in America. Bernt Julius Muus was the principal founder and Thorbjorn N. Mohn was the first president of St. Olaf College. Peter Laurentius Larsen and Ulrik Vilhelm Koren both helped found Luther College (Iowa).

O. Nelson was the founder of the N. O. Nelson Manufacturing Co. and Alfred M. Moen founded Moen, Inc.
In sports, Knute Rockne became one of the greatest coaches in college football history, while Babe Zaharias was named by the Guinness Book of Records as the most versatile female athlete of all time. Zaharias achieved outstanding success in golf, basketball and track and field athletics. Additionally, Stein Eriksen won the gold medal in the Giant Slalom event at the 1952 Winter Olympics, which were held in Oslo, Norway. He also won a silver medal in the slalom race. Eriksen was the first skier from outside the Alps to win an Olympic men's alpine gold medal. He also won three gold medals at the 1954 World Championships in Åre, Sweden, and a bronze medal at the 1950 World Championships in Aspen, Colorado. Shortly after his success in the 1952 Olympics, Eriksen moved to America where he continues to live. He worked as a ski-instructor and ski school-director at various ski schools such as Sugarbush in Vermont, and Aspen in Colorado. He is currently director of skiing at the Deer Valley Resort in Utah, and also serves as host of the Stein Eriksen Lodge, a ski lodge in Deer Valley, Utah.
In medicine, Earl Bakken developed the first wearable transistorized pacemaker and founded the Fortune 500 medical technology company Medtronic as well as the Bakken Museum. John H. Lawrence, is known as the father of nuclear medicine. As many historians claim, the genesis of this medical specialty in the United States took place in 1936, when John Lawrence took a leave of absence from his faculty position at Yale Medical School, to visit his brother Ernest Lawrence at his new radiation laboratory (now known as the Lawrence Berkeley National Laboratory) in Berkeley, California. 
In humanitarian work, Greg Mortenson, born in Minnesota, whose ancestors came from Tromsø in 1876, has worked since 1993 to build over 150 schools for girls in Pakistan and Afghanistan. He is the author of best-seller Three Cups of Tea, which has sold over 4 million copies in 49 countries, including Norway.
