The Rivière du Loup is a river in eastern Quebec, Canada, which empties on the south shore of Saint Lawrence River at the city of Rivière-du-Loup, which is part of the regional county municipality (RCM) Rivière-du-Loup, in the administrative region of Bas-Saint-Laurent.

This lake is located 36.5 km east of the southeast coast of the Gulf of St. Lawrence, 20.1 km southeast of the village center of Saint-Bruno-of-Kamouraska and 19.4 kilometers south-west of the village center of Saint-Athanase.

From Malin Rock, this edge advances towards the southwest in the St. Lawrence River over a length of 1.6 km, including the end where a marina is fitted.
