Great Bear Lake (Slave: Sahtú; French: Grand lac de l'Ours) is a lake in the boreal forest of Canada. It is the largest lake entirely in Canada (Lake Superior and Lake Huron are larger but straddle the Canada–US border), the fourth-largest in North America, and the eighth-largest in the world.[4] The lake is in the Northwest Territories, on the Arctic Circle between 65 and 67 degrees of northern latitude and between 118 and 123 degrees western longitude, 156 m (512 ft) above sea level.

The name originated from the Chipewyan word satudene, meaning "grizzly bear-water people". The Sahtu, a Dene people, are named after the lake. Grizzly Bear Mountain, or Sahoyue, on the shore of the lake also comes from Chipewyan, meaning "bear-large hill".[5][6]

Sahoyue (Grizzly Bear Mountain), a peninsula on the south side of the lake, and Edacho (Scented Grass Hills), another peninsula on the west side, form the Saoyú-ʔehdacho National Historic Site of Canada.[7][8]
