Saint-Basile is a geographic parish in Madawaska County, New Brunswick, Canada.

For governance purposes it is divided between the city of Edmundston, the St. Basile 10 Indian Reserve, and the Northwest rural district; the city and rural district are members of the Northwest Regional Service Commission.

Before the 2023 governance reform, the area now in the rural district formed the local service district of the parish of Saint-Basile.

The parish was named for the Roman Catholic church.

Saint-Basile was erected as Saint Basil in 1850 from Madawaska Parish.

In 1852 the parish's boundaries were extended northward to include territory awarded in the boundary settlement with the Province of Canada.

In 1874 the core of modern Edmundston was removed from Saint-Basile and added to Madawaska Parish.

In 1877 the newly erected Sainte-Anne Parish included part of Saint-Basile.

In 1896 the boundary along Green River was altered.

In 1920 part of Saint-Basile was erected as Rivière-Verte Parish.

In 1973 the name was officially changed to Saint-Basile.
