French Canadians (referred to as Canadiens mainly before the twentieth century; French: Canadiens français, pronounced [kanadjɛ̃ fʁɑ̃sɛ]; feminine form: Canadiennes françaises, pronounced [kanadjɛn fʁɑ̃sɛz]), or Franco-Canadians (French: Franco-Canadiens), refers to an ethnic group who trace their ancestry to French colonists who settled in France's colony of Canada beginning in the 17th century.

During the 17th century, French settlers originating mainly from the west and north of France settled Canada. It is from them that the French Canadian ethnicity was born. During the 17th to 18th centuries, French Canadians expanded across North America and colonized various regions, cities, and towns. As a result people of French Canadian descent can be found across North America. Between 1840 and 1930, many French Canadians immigrated to New England, an event known as the Grande Hémorragie.
