Saint-Charles-Garnier (French pronunciation: [sɛ̃ ʃaʁl ɡaʁnje]) is a parish municipality in Quebec, Canada.

Settlers began arriving in the area at the end of 1935.

They came mainly from Priceville, Saint-Fabien, Sainte-Flavie, Saint-François-Xavier-des-Hauteurs and Saint-Simon-de-la-Baie-Ha!

A Catholic service was opened in 1937 and the first parish priest was appointed.

The parish of Saint-Charles-Garnier was canonically erected in 1954.
