Rivière-Saint-Jean, Gaspésie–Îles-de-la-Madeleine, Quebec

Rivière-Saint-Jean is an unorganized territory in the Gaspésie–Îles-de-la-Madeleine region of Quebec, Canada. It is bisected by Quebec Route 198 that runs along the banks of the York River.

The territory is named after the Saint-Jean River that is considered one of the best salmon rivers in Quebec. This 90 km long river has its source in the Chic-Choc Mountains, about 5 km south of Murdochville, and runs in a south-east direction for the first 35 km, then east to the Bay of Gaspé. Portions of the river are protected in the Rivière-Saint-Jean Wildlife Reserve.
