The Baie des Rochers River is a tributary of the northwest shore of the St. Lawrence River, flowing into the town of Saint-Siméon, in the Charlevoix-Est Regional County Municipality, in the Capitale-Nationale administrative region, Quebec, Canada. The course of this river goes through the village of Baie-des-Rochers before going to the Bay of Rochers, in the St. Lawrence River.
This small valley is served by the "rue des Tours" and "rue de la Chapelle"; these two roads connect together at route 138 which goes along the northwest shore of the St. Lawrence River and passes over the Baie des Rochers River at the village of Baie des Rochers.
Forestry is the main economic activity of the sector; recreational tourism activities (including resort and tourist activities), 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 Baie des Rochers River rises at the mouth of Baie aux Rochers Lake (altitude: 200m (700feet)) in the forest zone.

From the mouth of Port aux Quilles Lake, the course of the Port aux Quilles River descends by traveling 9.9km (06.2miles) according to the following segments:
This toponym refers to the rocks all around the bay and on "Baie des Rochers Island" which is located in the middle of the bay.
The toponym "Rivière de la Baie des Rochers" was formalized on December 5, 1968 at the Bank of place names of the Commission de toponymie du Quebec.[3]
