Lake Sautauriski is a freshwater body crossed from north to south by the Sautauriski River, flowing in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in province of Quebec, in Canada.

The watershed area of Sautauriski Lake is mainly served on the east side by the route 175 which links the towns of Quebec and Saguenay.

The Sautauriski dam is located at its mouth, at the bottom of a bay in the southern part of the lake.

[2] Despite its small size, it is the largest of the 216 bodies of water in Jacques-Cartier National Park.

The toponym "Lac Sautauriski" was formalized on December 5, 1968, by the Commission de toponymie du Québec.
