The rivière du Castor (French pronunciation: [ʁivjɛʁ dy kastɔʁ], River of the Beaver) is a tributary of Rivière à l'Ours, flowing successively in the municipalities of Sainte-Hedwidge and Saint-Prime, in the Le Domaine-du-Roy Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada.

The Beaver River valley is served by the 3rd range road, the Marcel-Auclair road and the 6th range road.

Forestry and agriculture are the main economic activities in this valley.

The surface of the Beaver River is usually frozen from the beginning of December to the end of March, except the rapids areas; however, safe traffic on the ice is generally from mid-December to mid-March.
