The first settler in the village was Joseph Bertin in the early 19th century. The village was originally named Saint-Joseph, but changed in 1904 to avoid confusion with another Saint-Joseph near Memramcook.
The village was incorporated in 1978.
On 1 January 2023, Saint-Léolin amalgamated with the three other villages and all or part of four local service districts to form the new of Rivière-du-Nord.[2][3] The community's name remains in official use.[4]
