The Roscoe River is a waterway located above the Arctic Circle on the mainland of Northern Canada. It originates at 68.69861°N, -120.20972°W in western Kitikmeot Region, Nunavut, northwest of Bluenose Lake. The river passes through the Melville Hills and Tuktut Nogait National Park in the Northwest Territories, before emptying into Amundsen Gulf at its juncture with Dolphin and Union Strait, between Deas Thompson Point and Tysoe Point.
