The Cap-Rouge river (French: Rivière du Cap Rouge) is a river in the Sainte-Foy–Sillery–Cap-Rouge borough of Quebec City and in the city of Saint-Augustin-de-Desmaures, both cities in the Capitale-Nationale region of Quebec, Canada.[1][2][3]

The river begins on the slopes of Mount Bélair, at the foothills of the Laurentian Mountains, and flows 23.5 kilometres (14.6 mi) before ending in the Quebec City neighbourhood of Cap-Rouge as a left tributary of the Saint Lawrence River.[3] It is also at the junction of those rivers that is located the archeological site of Charlesbourg-Royal, the earliest known French settlement in North America.[4]

Its 82-square-kilometre (32 sq mi) watershed also encompasses parts of La Jacques-Cartier Regional County Municipality, L'Ancienne-Lorette, La Haute-Saint-Charles and Saint-Augustin-de-Desmaures.[3], where agricultural activities are found and which puts the river at risk of agricultural pollution. Measurements of ammoniacal nitrogen, nitrate and phosphorus were however all classified as "good" in 2016.[5]
