Contwoyto Lake is a lake in the Kitikmeot Region of the Canadian territory of Nunavut, located near the border with the Northwest Territories. With a total area of 1,034 km2 (399 sq mi),[1] it is the territories' tenth largest lake.

Lupin Mine is located near Contwoyto Lake. The lake is also the terminus of the Tibbitt to Contwoyto Winter Road from Tibbitt Lake in the Northwest Territories, Nunavut's only currently existing road access to the rest of Canada. In 2005, there was a proposal put forward to extend the winter road to a possible port at Bathurst Inlet.
