Great Slave Lake (French: Grand lac des Esclaves) is the second-largest lake in the Northwest Territories of Canada (behind Great Bear Lake), the deepest lake in North America at 614 m (2,015 ft), and the ninth-largest lake in the world. It is 480 km (298 mi) long and 19 to 109 km (12 to 68 mi) wide. It covers an area of 28,400 km (11,000 sq mi) in the southern part of the territory. Its volume is 2,090 km (501.7 cu mi,1.694 billion acre feet). The lake was named for the Slavey North American Indians.

The Hay and Slave Rivers are its chief tributaries. It is drained by the Mackenzie River. Though the western shore is forested, the east shore and northern arm are tundra-like. The southern and eastern shores reach the edge of the Canadian Shield. Along with other lakes such as the Great Bear and Athabasca, it is a remnant of a vast post-glacial lake.

The East Arm of Great Slave Lake is filled with islands, and the area is within Thaydene Nene National Park. The Pethei Peninsula separates the East Arm into McLeod Bay in the north and Christie Bay in the south. The only community in the East Arm is Lutselk'e, a hamlet of about 350 people, largely Chipewyan aboriginals of the Dene Nation.
