Location of the mouth of the Mattagami River in Ontario

The Mattagami River is a river in Northern Ontario.

The Nikolas 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).
