The rivière à Pierre (English: River of Pierre) is a tributary of the east bank of the Batiscan River, flowing in the unorganized territories of Lac-Blanc (township of Neilson) and Linton (township of Tonty), as well as in the municipality of Rivière-à-Pierre (township of Bois), in the Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.

The course of the "rivière à Pierre" descends on the northeast side of the Batiscan River and on the northeast side of the St. Lawrence River. This river is part of the hydrographic side of the Batiscan River which generally winds south to the north bank of the St. Lawrence River.

The upper course of the "Pierre river" is entirely in the forest zone up to Lac du Dépôt; as well as the lower part from the outlet of Lac Cinquante. The agricultural area is concentrated around the village of Rivière-à-Pierre. The river surface is generally frozen from mid-December until the end of March.

Since the mid-19th century, forestry has been the predominant activity in the "Pierre river" watershed. At the end of the 19th century, the extraction of marble stones developed, as well as agriculture and recreational tourism.

The Canadian National railway runs along the "Pierre river" between the confluence of the Blanche River and the "Sainte-Anne rapids".
