The Canet River is a tributary of Matagami Lake, flowing into the territory of Eeyou Istchee Baie-James (municipality), in the administrative region of Nord-du-Québec, in Quebec, in Canada.

The Canet River flows in forest and marsh zone (especially in its upper part), East of Lake Matagami.

Road transport to James Bay is the main economic activity of this watershed.

The Canet River originates from a marsh area at an altitude of 274 metres (899 ft).

The Matagami Lake empties on the North-West side by the North Bay in the Nottaway River.
