Saint-Louis-de-France, Administrative sector in Trois-Rivières, Canada.

Saint-Louis-de-France is one of the six sectors of Trois-Rivières, Quebec, with about 7,246 inhabitants before 2002. It was a parish municipality from 1904 to 1993, then a city from 1993 to 2002, before being amalgamated into Trois-Rivières. The sector lies at coordinates 46.42220, -72.62550.

Founded in 1904, Saint-Louis-de-France was a parish municipality until 1993, when rapid population growth and urbanization led the government to grant it city status in July 1993. On January 1, 2002, it was amalgamated with Sainte-Marthe-du-Cap, Cap-de-la-Madeleine, Trois-Rivières, Trois-Rivières-Ouest and Pointe-du-Lac to form the present city of Trois-Rivières. Its post office carried the name Saint-Louis-de-Champlain from 1902 to 1967.

The name Saint-Louis-de-France honours Louis IX, canonised in 1297, who was the first patron of the former Vieilles-Forges mission on this territory; another explanation points to Bishop Louis-François Laflèche, who received the petitions to open the parish. The local post office was called Saint-Louis-de-Champlain from 1902 to 1967, a reference to the old county.

The sector is accessible by local roads and public transportation that connect residential areas to downtown Trois-Rivières. Visitors will find grocery stores, schools, and small parks throughout the neighborhood.

The name is explained by the fact that Louis IX (1214-1270), canonised in 1297, was the first patron of the former Vieilles-Forges mission, founded in 1740, to which Saint-Louis-de-France once belonged. Another explanation points to Bishop Louis-François Laflèche (1818-1898) of Trois-Rivières, who received the petitions to open the new parish.
