Tongan Americans are Americans who can trace their ancestry to Tonga, officially known as the Kingdom of Tonga. There are approximately 57,000 Tongans and Tongan Americans living in the United States, as of 2012.  Tongans are considered to be Pacific Islanders in the United States Census, and are the fourth largest Pacific Islander American group in terms of population, after Native Hawaiians, Samoan Americans, and Guamanian/Chamorro Americans.
The Tongans have emigrated to the United States or its territories since 1916, when some people of this island immigrated to Laie, a census-designated place in Hawaii, which was then an American territory but not yet a state. However, it was not until the end of World War II when many more Tongans immigrated to the United States. Most of them were missionaries, who emigrated to the United States to work in several religious and cultural centers. On the other hand, most of Tongan immigrants to the United States came since 1970 because most Tongans are farmers[ citation needed] but number of lands are limited on their country and not everyone has been able to get one. The number of people of Tongan origin has grown every decade. By 1980, 6,200 people of this origin were living in the US, and by in 1990 that number had increased to 17,600.  By 2000, there were 31,891 Tongan people living in the United States. 
Tongan immigration has been favored primarily by The Church of Jesus Christ of Latter-day Saints (LDS Church), who help them obtain visas (both studies and work) and employment and even they help them to get couples, when they are in marriageable age. 
The San Francisco Bay Area has the largest concentration of ethnic Tongans outside of Tonga, with an estimated population of 13,000 in San Mateo County alone, concentrated especially in the city of East Palo Alto.  Within San Mateo County, the city of San Mateo, San Bruno, and South San Francisco have sizable Tongan populations. Other Bay Area cities with significant Tongan populations include the East Bay cities of Oakland, San Leandro, Concord, and Pittsburg. Smaller communities can be found in Santa Clara County, mainly in Mountain View.  There are 500 people of Tongan descent living in Portland, Oregon (0.1% of the city's population).
The state of Utah has a large presence of Tongan Americans, and a significant Pacific Islander population in general. Tongans first started immigrating to Utah because of their attraction to the abundant amount of LDS congregations in the state. As of 2011, Utah has around 30 branches of Tongan Latter-day Saint churches. About one of four people of Tongan descent living in the U.S. live in Utah. Salt Lake County has more than 9,000 Tongan Americans in residence. Nearly 3,000 people of Tongan descent live in Salt Lake City alone. 
Euless, Texas has a sizable Tongan community. At least ten Tongan churches are present in Euless. Trinity High School is also well known in the local area for their tradition of beginning Friday night football games with the culture's traditional war cry, the Kailao. 
Other American cities with significant Tongan American populations include: the Greater Los Angeles Area city of Inglewood, Hawthorne, and the Inland Empire subregion. Anchorage, Alaska; Kona, Hawaii; Lahaina, Hawaii, and Reno, Nevada.
