The Cook River is a tributary of the Jacques-Cartier River, flowing in Jacques-Cartier National Park, in the unorganized territory of Lac-Croche, in the La Jacques-Cartier Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, Canada.
The upper part of the Cook River valley is served by secondary forest roads.[1]
Forestry is the main economic activity in the sector; recreational tourism activities, second.
The surface of the Cook River (except rapids) is generally frozen from early December to late 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.

The Cook River toponym was formalized on November 7, 1985 at the Place Names Bank of the Commission de toponymie du Québec.[3]
