The Cassian River is a tributary of the Jacques-Cartier River, flowing in the municipalities of Saint-Gabriel-de-Valcartier and Stoneham-et-Tewkesbury, in the La Jacques-Cartier Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, Canada.^[1]

The Cassian River valley is served by secondary forest roads. The lower part is served indirectly by the Tewkesbury road which passes on the east side of the Jacques-Cartier river.^[2]

Forestry is the main economic activity in the sector; recreational tourism, second. The Tantaré Ecological Reserve covers part of Cassian Lake.^[3] In addition, the hydrographic slope of the Cassian river includes 4.77 square kilometres (1.84 sq mi) in Jacques-Cartier National Park.

The surface of the Cassian 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; the spring flood occurs in March or April.
