Louisiana French is an umbrella term for the dialects and varieties of the French language spoken traditionally by French Louisianians in colonial Lower Louisiana. As of today Louisiana French is primarily used in the state of Louisiana, specifically in its southern parishes.

The French Louisianians, also known as Louisiana French, are Latin French people native to the states that were established out of French Louisiana. They are commonly referred to as French Creoles. Today, the most famous Louisiana French groups are the Alabama Creoles, Louisiana Creoles, and the Missouri French.
