The Rivière Portneuf is a tributary of the north shore of the Saint-Laurent river, crossing the municipalities of Saint-Raymond, Pont-Rouge, Sant-Basile and Portneuf, in the Portneuf Regional County Municipality, in the administrative region of the Capitale-Nationale, in the province of Quebec, in Canada.

The Portneuf river valley is mainly served by route 138, chemin Neuf, chemin du rang Saint-Angélique, chemin du Grand Rang (route 365), chemin de Bourg-Louis, chemin de la Grande Ligne and chemin du Lac Sept-Îles-Sud.^[1]

Except for the segments passing through a hamlet of Saint-Raymond, in the village of Saint-Basile and the village of Portneuf, agriculture and forestry constitute the main economic activities of the sector.

The surface of the Portneuf River (except the rapids areas) is generally frozen from the beginning of December to the end of March; safe circulation on the ice is generally done from the end of December to the beginning of March. The water level of the river varies with the seasons and the precipitation.
