Mattagami River
The Mattagami River is a river in Northern Ontario, Canada.

The Mattagami flows from its source at Mattagami Lake in geographic Gouin Township in the Unorganized North Part of Sudbury District, on the Canadian Shield southwest of Timmins, to Portage Island in geographic Gardiner Township in the Unorganized North Part of Cochrane District, in the Hudson Bay Lowlands. Here the Mattagami's confluence with the Missinaibi River forms the Moose River, about from that river's tidewater outlet at James Bay. The Mattagami River flows through the city of Timmins as well as the town of Smooth Rock Falls and its drainage basin encompasses .

The Mattagami's name comes from the Ojibwe and means either "the start of water" ("maadaagami") or "turbulent water" ("madaagami"), but the local Ojibwe population claim "Mattagami" is a corrupted form of "confluence" ("maadawaagami"). According to the Mattagami First Nation, Mattagami means "Meeting of the Waters".
