The Rivière des Roches (English: River of rocks) is a tributary of the west bank of the Sainte-Anne River, on the north bank of the Saint Lawrence River. This river flows in the unorganized territory of Lac-Jacques-Cartier and in the municipality of Saint-Ferréol-les-Neiges, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.

The upper part of this valley is mainly served by the rang Saint-Nicolas road which passes on the northeast side. The lower part is served by avenue Royale and by the chemin du rang Saint-Nicolas which passes on the southwest side. Forestry is the main economic activity in this valley; recreational tourism activities, second; agriculture, third.

The surface of the Rivière des Roches is generally frozen from the beginning of December until the end of March; however, safe traffic on the ice is generally from mid-December to mid-March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
