The Great Bear Lake (Slavey: Sahtú /ˈsɑː.tuː/, French: Grand lac de l'Ours) is the largest lake entirely in Canada (Lake Superior and Lake Huron straddling the Canada-US border are larger), the fourth largest in North America, and the eighth largest in the world. 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 words "Satudene" in Denesuline meaning “grizzly bear water people.” The Sahtu Dene people are named after the lake. Grizzly Bear Mountain on the shore of the lake also comes from Denesuline, meaning, “bear large hill.”
The Sahoyue (Grizzly Bear Mountain) peninsula on the south side of the lake and the Edacho (Scented Grass Hills) peninsula on the west side form the Saoyú-ʔehdacho National Historic Site of Canada.
