The history of the French in Baltimore dates back to the 18th century. The earliest wave of French immigration began in the mid-1700s, bringing many Acadian refugees from Canada's Maritime Provinces. The Acadians were exiled from Canada by the British during the French and Indian War. Later waves of French settlement in Baltimore from the 1790s to the early 1800s brought Roman Catholic refugees of the French Revolution and refugees of the Haitian Revolution from the French colony of Saint-Domingue.
In 1920, 626 foreign-born White people in Baltimore spoke the French language.
As of the 2000 United States Census the French American community in the Baltimore metropolitan area numbered 47,234 (1.9% of the area's population) and an additional 10,494 (0.4%) identified as French Canadian American. This places the Baltimore area's total population of French descent at 57,728, which is 2.3% of the area's population. The Census also found that the French language (including French Creole) is spoken at home by 5,705 people in Baltimore.
