The Pokotciminikew River is a tributary of the North Shore of the Kakospictikweak River, flowing into the territory of the town of La Tuque, in the administrative region of Mauricie, in Quebec, Canada. The course of this river successively crosses the cantons of Pfister, Balete and Mathieu.
Forestry is the main economic activity of the river valley; recreational tourism activities, second. The valley is served by a few branches of forest roads.
The surface of the Pokotciminikew River is usually frozen from mid-November to the end of April; however, safe ice circulation is generally from early December to late March.
The toponym "Rivière Pokotciminikew" was formalized on September 6, 1984 at the Commission de toponymie du Québec.
