The Gosselin River flows in the western part of the city of La Tuque, in the administrative region of Mauricie, in Quebec, in Canada.

Forestry has always been the dominant economic activity of this hydrographic sub-catchment.

The surface of the river is generally frozen from mid-November to mid-April.

This lake is located at 49.0 kilometres (30.4 mi) west of the village of Parent at 27.0 kilometres (16.8 mi) southeast of the village of Clova, Quebec through the Canadian National Railway.

The toponym "Gosselin River" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
