The Mattagami River is a river in Northern Ontario, Canada.
The Mattagami flows 443 kilometres (275 mi) from its source at Mattagami Lake in geographic Gouin Township[1] in the Unorganized North Part of Sudbury District, on the Canadian Shield southwest of Timmins,[2] to Portage Island in geographic Gardiner Township[3] in the Unorganized North Part of Cochrane District, in the Hudson Bay Lowlands.[4] Here the Mattagami's confluence with the Missinaibi River forms the Moose River, about 100 kilometres (60 mi) from that river's tidewater outlet at James Bay.[5] The Mattagami River flows through the city of Timmins as well as the town of Smooth Rock Falls[5] and its drainage basin encompasses 37,000 square kilometres (14,000 sq mi).[2]
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".
