Black Lake (Chipewyan: Tazen Tuwé) is a Denesuline First Nations band government in the boreal forest of northern Saskatchewan, Canada.

It is the main administrative headquarters of the Black Lake Denesuline Nation Indian reserve with a land base of over 32,000 hectares (79,000 acres).

[2] Formerly, the Black Lake band used the name "Stony Rapids", which is now the name of a separate community 20 kilometres (12 mi) northwest and downstream on the Fond du Lac River, not on reserve land.

The community is served by air by Black Lake Water Aerodrome, and by Stony Rapids Airport.

The hospital, located on reserve land (Chicken 224) adjacent to the northern hamlet of Stony Rapids, is part of the Athabasca Health Authority.
