List of Louisiana parishes by French-speaking population

The list of Louisiana parishes by French-speaking population was created from the 2000 United States census.^[1] The Census Bureau collects data on languages spoken at home by inhabitants of Louisiana five years of age or more. Responses "French" and "Cajun" are included. In 2010, statewide, out of a population 5 years and older of 4,152,122, some 179,750 people reported French as their home language, while 14,365 reported "Cajun". A further 4,465 who reported French Creole, which includes both Louisiana's Kouri-Vini and Haiti's Kreyòl, are not counted below.

French spread in Louisiana. Parishes marked in yellow are those where 4–10% of the 2015 population speak French or Cajun French at home, orange 10–15%, red 15–20%.

The 2015 update comes from American Community Survey data. In 2005 the U.S. Census Bureau retired its census long form, instead using ACS estimates to track language use. For 2015, a total of 107,616 people in Louisiana (5 years old and older) were estimated to speak French, including Cajun French, Patois, and other varieties of French. An additional 7,209 people were estimated to speak French Creole, but are not included in the table below. The 2017–2021 ACS update estimated 57,640 French speakers and 14,020 speakers of "Cajun French and other French languages." As of July 2025^[update], a parish-by-parish breakdown of French speakers over the age of 5 was not available.^[2]
