The French language is spoken as a minority language in the United States. Roughly 2.1 million Americans over the age of five reported speaking the language at home in a federal 2010 estimate, making French the fourth most-spoken language in the nation behind English, Spanish, and Chinese (when Louisiana French, Haitian Creole and all other French dialects and French-derived creoles are included, and when Cantonese, Mandarin and other varieties of Chinese are similarly combined).

Several varieties of French evolved in what is now the United States: Louisiana French, spoken in Louisiana by descendants of colonists in French Louisiana New England French, spoken in New England by descendants of 19th and 20th-century Canadian migrants Missouri French, spoken in Missouri by descendants of French settlers in the Illinois Country Muskrat French, spoken in Michigan by descendants of habitants, voyageurs and coureurs des bois in the Pays d'en Haut Métis French, spoken in North Dakota by Métis people

More recently, French has also been carried to various parts of the nation via immigration from Francophone countries and regions. Today, French is the second most spoken language (after English) in the states of Maine, Vermont and New Hampshire. In Louisiana, it is tied with Spanish for second most spoken if Louisiana French and all creoles such as Haitian are included. French is the third most spoken language (after English and Spanish) in the states of Connecticut and Rhode Island.

As a second language, French is the second most widely taught foreign language (after Spanish) in American schools, colleges and universities. While the overwhelming majority of Americans of French ancestry grew up speaking only English, some enroll their children in French heritage language classes.

Dialects and varieties

There are three major groups of French dialects that emerged in what is now the United States: Louisiana French, Missouri French, and New England French (essentially a variant of Canadian French).

Louisiana French is traditionally divided into three dialects, Colonial French, Louisiana Creole French, and Cajun French. Colonial French is traditionally said to have been the form of French spoken in the early days of settlement in the lower Mississippi River valley, and was once the language of the educated land-owning classes. Cajun French, derived from Acadian French, is said to have been introduced with the arrival of Acadian exiles in the 18th century. The Acadians, the francophone inhabitants of Acadia (modern Nova Scotia, New Brunswick, Prince Edward Island, and northern Maine), were expelled from their homeland between 1755 and 1763 by the British. Many Acadians settled in lower Louisiana, where they became known as Cajuns (a corruption of "Acadians"). Their dialect was regarded as the typical language of white lower classes, while Louisiana Creole French developed as the language of the black community. Today, most linguists regard Colonial French to have largely merged with Cajun, while Louisiana Creole remains a distinct variety.

Missouri French was spoken by the descendants of 17th-century French settlers in the Illinois Country, especially in the area of Ste. Genevieve, St. Louis, and in Washington County. In the 1930s there were said to be about 600 French-speaking families in the Old Mines region between De Soto and Potosi. By the late 20th century the dialect was nearly extinct, with only a few elderly speakers able to use it. Similarly, Muskrat French is spoken in southeastern Michigan by descendants of habitants, voyageurs and coureurs des bois who settled in the Pays d'en Haut.

New England French, essentially a local variety of Canadian French, is spoken in parts of the New England states. This area has a legacy of significant immigration from Canada, especially during the 19th and the early 20th centuries. Some Americans of French heritage who have lost the language are currently attempting to revive it. Acadian French is also spoken by Acadians in Maine in the Saint John Valley.

Métis French is spoken by some Métis people in North Dakota.

Ernest F. Haden identifies the French of Frenchville, Pennsylvania as a distinct dialect of North American French. "While the French enclave of Frenchville, Pennsylvania first received attention in the late 1960s, the variety of French spoken has not been the subject of systematic linguistic study. Haden reports that the geographical origin of its settlers is central France, as was also the case of New Orleans, but with settlement being more recent (1830–1840). He also reports that in the 1960s French seemed to be on the verge of extinction in the state community."
