The Loutre River is a tributary of the northwest shore of the St. Lawrence River, flowing into the town of La Malbaie, between the towns of Cap-à-l'Aigle and Saint-Fidèle, in the Charlevoix-Est Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, in Canada. The course of this river flows into the St. Lawrence in the hamlet of Bas-de-l'Anse, northeast of the town of La Malbaie.
The valley of this watercourse is served by route 138 (Malcolm-Fraser Blvd.) which runs along the northwest shore of the St. Lawrence River and by route Sainte-Mathilde East.
Forestry is the main economic activity of the sector; recreational tourism activities (including resort and bed and breakfasts), second.
The surface of this stream is generally frozen from mid-December to late-March. Nevertheless, safe ice traffic is generally from late December to mid-March.

The toponym "rivière à la Loutre" was formalized on December 5, 1968 at the Bank of place names of the Commission de toponymie du Quebec.[3]
