Baker Lake is a hamlet in the Kivalliq Region, in Nunavut on mainland Canada. Located 320 km (200 mi) inland from Hudson Bay, it is near the nation's geographical centre, and is notable for being Nunavut's sole inland community. The hamlet is located at the mouth of the Thelon River on the shore of Baker Lake. The community was given its English name in 1761 from Captain William Christopher who named it after Sir William Baker, the 11th Governor of the Hudson's Bay Company.

Nunavut is the largest and northernmost territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the Nunavut Act and the Nunavut Land Claims Agreement Act, which provided this territory to the Inuit for independent government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map in half a century since the province of Newfoundland was admitted in 1949.
