The Thumb is a region and a peninsula of the U.S. state of Michigan, so named because the Lower Peninsula is shaped like a mitten. The Thumb area is generally considered to be in the Central Michigan region, located east of the Tri-Cities, and north of Metro Detroit. The region is also branded as the Blue Water Area of Michigan.
The counties which constitute the Thumb are those forming the extended peninsula that stretches northward into Lake Huron and Saginaw Bay. There is no formal declaration for which of these counties are part of the Thumb. While virtually all definitions of The Thumb include Huron, Tuscola, and Sanilac counties, and most common definitions are extended to include Lapeer and St. Clair counties as well.

The Thumb region is very flat with fertile soil, the reason for its historical role as a chiefly agricultural area. Major agricultural products include sugar beets, navy beans,  corn, fruits, and fish from the Saginaw Bay and Lake Huron. Manufacturing – particularly concerning the Automotive Industry – is also prevalent in Michigan's Thumb. Many different types of industries can be found in the thumb, mostly located in the southern portion of the region near the larger metropolitan areas of Detroit and Flint.
The Thumb has many notable businesses, many linked to agriculture.

Some towns, such as Bay Port, Caseville, Harbor Beach, Lakeport, Lexington, Port Austin, Port Hope, Port Huron, Port Sanilac, Sebewaing, and St. Clair enjoy seasonal tourism, due to their locations on Lake Huron, Saginaw Bay, or St. Clair River. Tourism and farming drive the local economy.
The Tip of The Thumb Heritage Water Trail is a nonprofit citizens organization working with the Huron County Parks to establish and maintain a water trail along Michigan's Lake Huron's shoreline. 
Few of the residents commute for work to Metropolitan Detroit or Flint or the Tri-Cities. Large cities in the Thumb area are Vassar, Port Huron, Lapeer, Marysville, St. Clair, Sandusky, Bad Axe, and Caro. The majority of these cities are in the southern portion of the Thumb.
Unique features in the area include the following:
- Algonac, known as the Venice of Michigan because of its many canals, is a part of the largest freshwater delta in the world, that of the St. Clair River into Lake St. Clair.
- Bad Axe was named after a broken axe found lodged in the knot of a tree at the clearing of the settlement's chief crossroads. 
- Bay Port, is the world's largest freshwater fishing port.[ citation needed]
- Harbor Beach is the home of the largest man-made harbor and the Harbor Beach Light.
- Harvest Wind Farm, an electrical generation project of Exelon Wind and Wolverine Power Supply Cooperative. Harvest II is scheduled for completion in December 2012.

- Caseville is the home of the annual Cheeseburger in Caseville festival, a hometown festival devoted to Jimmy Buffett's song " Cheeseburger in Paradise".
A favorite of tourists who visit this area is traveling the Lake Huron and Saginaw Bay shoreline via M-25 (formerly US Highway 25 until 1973). M-25 starts at the end of I-69/ I-94 in Port Huron at the foot of the Blue Water Bridge and ends in Bay City. The whole highway is about 150 miles (240 km), and passes through quaint cities and villages. Located along Lake Huron through which M-25 passes are five lighthouses: Fort Gratiot Lighthouse, Port Sanilac lighthouse, Pointe aux Barques Lighthouse, Harbor Beach Light, and the Port Austin Lighthouse.
The Great Lakes Circle Tour is a designated scenic road system connecting all of the Great Lakes and the St. Lawrence River.  Many visitors choose to begin the circle tour in Port Huron, from which they can circle Lake Huron. M-25 winds around the Thumb and along the Saginaw Bay to Saginaw and Bay City. Lexington and Port Austin feature beaches and boardwalks that are favorites with visitors.

Huron County is located at the tip of the thumb. The county is surrounded on three sides by water –
Saginaw Bay and
Lake Huron, and has over 90 miles (140 km) of shoreline, from
White Rock on
Lake Huron to
Saginaw Bay, and more shoreline parks than any other county in the state.
The county's economy relies on agriculture and ranks as one of the top agricultural counties in Michigan. Rich farmland inland produces beans, sugar beets and grain, including most of the world's supply of navy beans.  Tourism is also important to Huron County with bay front and lakefront towns such as Sebewaing, Caseville, Port Austin, Port Hope, and Harbor Beach, attracting tourists from all over. Huron County borders the Saginaw Bay and Lake Huron. There are two state parks – Sleeper State Park and Port Crescent State Park. Three roadside parks – Jenks Park, Brown Park, and White Rock Park. Also, Huron County maintains nine county parks along the shoreline, which are Caseville Park, Lighthouse Park, Stafford Park, McGraw Park, Philp Park, Port Austin Bird Creek Park, Wagener Park, Oak Beach Park, and Sebewaing Park.
The county seat is Bad Axe, located in the center of the county.
The County of Sanilac has the largest area of land in The Thumb. Like other counties, Sanilac has fertile and flat land, great for growing crops. Towns like Lexington and Port Sanilac bring in many tourists from the Detroit Area. Sandusky is the county seat and largest city.
Like Huron County, Tuscola is mostly dependent on agriculture. Industries such as sugar refining and ethanol processing, as well as growing various grains and beans, make up most of the economy. Caro, one of the largest cities in The Thumb (the largest if you exclude St. Clair and Lapeer Counties), is named after Cairo, Egypt and is the county seat. Tuscola County only has 18 miles (29 km) of shoreline along Saginaw Bay, so it is not as dependent on tourism as the other counties in the area. Tuscola County is economically tied to the surrounding region as well as to the Saginaw, Bay City, and Flint areas.
The origin of the name of the county is often disputed, but it may have derived from the French words "la pierre", meaning "the stone." This name could be a reference to the rounded stones, or flint pebbles, found in the rivers and streams throughout the area. Another theory, is that it may simply be an English variation of "Le Pays Plat", meaning "the flat land", which is one of the original names given to the area by the French, and can be found on many early fur trader maps of the area. The idea is that "Le Pays" may have evolved into the current pronunciation, "Lapeer."
Lapeer County is in many ways different from the other counties of The Thumb. First, it is heavily influenced by its proximity to Flint and Detroit, so as a result, its economy depends more heavily on manufacturing, than the other counties of the region. Second, although agriculture is still a key economic factor in Lapeer County, it is just not as important to the economy as in the other counties. Although there are still a few large scale farms located in the county, the numbers are not found to the same extent, and these days, most farming in Lapeer now takes place on smaller, independent farms, which usually supply the local markets only. Lastly, in addition to its economic and agricultural differences, Lapeer County's geography is also very different from the other counties of The Thumb. It's topography is generally, gently rolling to quite hilly, and unlike its neighbors, which are flatter, and border on Lake Huron or Lake St. Clair, Lapeer County is landlocked. The County still has hundreds of acres of inland lakes such as Barnes Lake-Miller Lake, Lake Neppessing, The Holloway Reservoir, Big Fish Lake, and Lake Metamora, and several state recreation areas, including the Ortonville Recreation Area and the Metamora-Hadley Recreation Area, which still bring in many campers and tourists.
St. Clair County has the largest population in The Thumb, and is considered part of the Metro Detroit MSA. Many residents farther north in The Thumb, especially Sanilac County, travel to Port Huron for shopping and work. It is the farthest county to the east in Michigan, and most of the eastern border is the St. Clair River, which separates Michigan from Ontario. For the most part, St. Clair County is flat and agriculturally dominating in the north and west, but also has steep hills and small canyons near the Black River, although manufacturing dominates in and around Port Huron.
Some areas of the thumb are debatable, but nearly all definitions will include Huron, Sanilac, and Tuscola Counties, known as the tri-county region. Disputed areas include:
- St. Clair County, especially the southern portion, as the county is considered part of Metro Detroit by the Census Bureau.
- Lapeer County
- Richmond and northern Macomb County.
- Genesee County, although it has a more urban setting, may be seen as part of the thumb peninsula.
The Blue Water Area is another term describing the Thumb of Michigan. The term is usually used in respect to St. Clair County, and surrounding areas. The title is also extended to include all of Michigan's Thumb. The name is derived from the flowing blue water of St. Clair River, connecting Lake Huron to Lake St. Clair, and the namesake Blue Water Bridge which spans over the river, connecting Port Huron to Sarnia, Ontario. A similar name, "Blue Water Country" is used to describe the same region on the Canadian side.
Discover the Blue is a promotion by the Blue Water Area Convention and Visitor's Bureau  to attract visitors to the shoreline of eastern Michigan. Communities participating in Discover the Blue range from Algonac (at the southern end of the Thumb) to Port Austin (at the tip of the Thumb).
- The Thumb's landscape ranges from a flat sandy plain, that hugs the shores of Lake Huron and Saginaw Bay, to a gently rolling topography, which is fertile and well suited for agriculture. Perhaps, the most unusual geographic formation, however, is a rugged glacial ridge, known collectively as the Hadley Hills, which extends in a northeasterly direction through the center of The Thumb, from the southwestern portion of the peninsula.
- All counties except for Lapeer border the Saginaw Bay or Lake Huron.
- The places with the highest elevation are all associated with the Hadley Hills, and are located in Lapeer County, they are: Pinnacle Point, at 1,262 feet (385 m), Kerr (Cemetery) Hill, at 1,258 feet (383 m), both in Hadley Township, Mt Christie, at 1,251 feet (381 m), in Metamora Township, and a point near Mayville, reaching up to 1,050 feet (320 m) above sea level.
- The lowest point in the Thumb region is the shore of Lake St. Clair, at a low of 574 feet (175 m) above sea level.
- Huron County is very flat and is home to wind turbines and large fields.
- The "tip of the Thumb" is Pointe Aux Barques, between Port Austin and Grindstone City.
- Marlette is also called the "heart of the Thumb" because of its central position on the peninsula.
The Thumb has many waterways.
- Cass River has many branches, one of which flows into the Shiawassee River in the Shiawassee National Wildlife Refuge at less than 1 mile (2 km) from where the Shiawassee merges with the Tittabawassee River to form the Saginaw River
- The Pinnebog, Shebahyonk, and Pigeon rivers all rise in the center of Huron County and empty into the Saginaw Bay.
- St. Clair River, connects Lake Huron to Lake St. Clair, and is the farthest east border in Michigan. It forms a low impression in eastern St. Clair County, and has a delta at its mouth (North America's largest freshwater delta), which includes Harsens Island and Walpole Island, Ontario. Ferries cross the river at Algonac and Marine City, these being international border crossings.
- Black River rises near Minden City and flows into the St. Clair River at Port Huron. The Black River forms a basin in Sanilac County, and northern St. Clair County.
- The north branch of the Flint River lies in northern Lapeer County. It rises near North Branch. The southern branch flows through the central and southern portion of Lapeer County, originates in Brandon, Atlas, Hadley, and Metamora townships before merging with the North Branch just north of the Holloway Reservoir.
Persons of European ancestry have formed the overwhelming majority of the population since the late 18th century, and have left the most significant imprint on the culture of The Thumb. The French were the first Europeans to arrive and as a result they influenced much of the early culture. However, the French were mostly engaged in the fur trading and lumber industries, so their settlement of the area was sparse. It wasn't until the British seized control in 1763, after the French and Indian War, that larger numbers of settlers began to arrive. Many of these new settlers were sent into the area by the British from Canada in an effort to establish their dominance over the Great Lakes. In 1783, control of The Thumb was officially transferred to the newly formed United States, after the American Revolution and by the Treaty of Paris. The British however, remained the dominant influence culturally until the War of 1812 firmly established the United States as the owner of the region. This final transfer of control allowed for the organization of the Northwest Territory, and American settlement of Michigan and The Thumb.
As a result of this history, the land was settled mostly by English and Scots-Irish immigrants, many of whom arrived from Canada. Other settlers of the same ancestry migrated from eastern states such as New York, and Pennsylvania, as well as from New England. Later 19th and 20th century residents included Polish and German immigrants who migrated from Europe through the Detroit area. Many of the customs, much of the regional lifestyle, and even the local accent, strongly reflect these origins. Examples include polka shows on some local radio stations, and various ethnic festivals such as the Polkafest, in Kinde.
The European pioneers encountered aboriginal peoples during the settling of the area, which heavily influenced the culture of The Thumb. Most of this interaction was predominately with members of the Fox and Sauk tribes, already living in the area for centuries. There may have also been other tribes in the area such as the Potawatomi, Ojibwe, and Kickapoo, but they would have been transient tribes, or found in very small numbers. All native Thumb area tribes are members of the Algonquian peoples, a large language family. Other tribes who migrated later into the area included the Wyandot ( Huron), an Iroquoian language-speaking people; and the Ottawa. The displacement of native peoples was part of the history of the settling of North America, and most of the area has been developed along the model of European-American practices.[ citation needed]
- The Port Huron area is one of oldest European settlements in the state of Michigan, first settled by French colonists.
- Colonial-era forts such as Fort Gratiot (north of Port Huron) and Fort Sinclair (near present-day St. Clair) were built along the St. Clair River.
- Bad Axe was named so because Captain Rudolph Papst found an old axe in 1861, when he was clearing land for the present-day Huron County seat.
- The great Thumb Fire took place on September 5, 1881 in the Thumb area of Michigan. The fire, which burned over a million acres (4,000 km²) in less than a day, was the consequence of drought, hurricane-force winds, heat, the after-effects of the Port Huron Fire of 1871 and the ecological damage wrought by the era's logging techniques of clear cutting.
- The Great Lakes Storm of 1913 was a November blizzard with hurricane-force winds which devastated the Great Lakes Basin in the United States Midwest and the Canadian province of Ontario. The storm battered and overturned ships on four of the five Great Lakes, particularly Lake Huron.

The border between Port Huron, Michigan and Sarnia, Ontario is one of the busiest connections between Canada and the US. Crossings include the two Blue Water Bridges and the two St. Clair River Railway Tunnels. Ferries also connect to Canada at Marine City and Algonac.
(organized by numbers)
- I-69 begins at the Blue Water Bridge, proceeds west through Flint, then Lansing, and then turns south to Angola, Indiana.
- I-94 has its eastern terminus at the U.S. side of the Blue Water Bridge in Port Huron, Michigan, at the Sarnia, Ontario, Canada border, where together with I-69 it meets Ontario Highway 402.
- M-25 is a highway of an arc-like shape closely following the outline of the Thumb along the Lake Huron/Saginaw Bay shoreline between Port Huron and Bay City. It is generally a scenic drive.
- M-46 is a cross peninsular road, running across the mitten and the Thumb—from Port Sanilac on the Lake Huron shore; through Saginaw near Saginaw Bay; and then on to Muskegon on the Lake Michigan shore.  This east-west surface route nearly bisects the Lower Peninsula of Michigan latitudinally.
- M-53 (Van Dyke Road) is a gateway route to The Thumb of Michigan, carrying vacationers to the resorts and cottages on Saginaw Bay and Lake Huron in the vicinity of Caseville and Port Austin. It goes up the middle of the Thumb, and directly connects in Macomb County, Michigan to the M-53 expressway. It is an important route for agricultural and manufactured goods.
Area Amtrak stations are in Lapeer, Port Huron, and Flint. Local railroads are the Grand Trunk Western Railroad, CSX Transportation, Canadian National Railway, and the Huron and Eastern Railway. Pere Marquette Railway was a railroad that had lines throughout the Thumb; its lines are now either abandoned or in use by CSX, or Huron and Eastern.
The only international airport in the Thumb is St. Clair County International Airport about 6 miles (9.7 km) outside Port Huron. City airports include: Caro Municipal, Dupont-Lapeer Airport, Huron County Memorial Airport, Marine City Airport, Marlette Municipal, Sandusky City, and Yale Airport. Scheduled airline service is available from MBS International Airport  in Freeland, Michigan and Flint Bishop International Airport.  While neither of these airports is in the Thumb, both are relatively close by.
Area code 989 covers about half of the Thumb: Huron, Tuscola, and far northern Sanilac County (and the Marlette, Michigan area). The Thumb's other half is covered by area code 810, which takes in most of Sanilac, Lapeer, Genesee and Saint Clair Counties. All of Macomb County is served by area code 586, as is a small part of south-western Saint Clair County.
