The Saint-Louis River is a tributary of the Valin River, flowing on the northwest shore of the Saint Lawrence River, in the unorganized territory of Mont-Valin and the municipality of Saint-David-de-Falardeau, in the Le Fjord-du-Saguenay Regional County Municipality, in the administrative region of Saguenay-Lac-Saint-Jean, in the Province of Quebec, in Canada.
The forest road R0201 serves most of the hydrographic slope of the Saint-Louis river, for the needs of forestry and recreational tourism activities. The mouth of this river flows to the northwest limit of the Monts-Valin National Park.
Forestry is the main economic activity in the sector; recreational tourism, second.
The surface of the Saint-Louis River is usually frozen from the end of November to the beginning of April, however the safe circulation on the ice is generally made from mid-December to the end of March.
