The Tessier Lake is a freshwater body located on the south side of the southwestern part of the Gouin Reservoir, in the territory of the town of La Tuque, in the region of Mauricie, in the province of Quebec, in Canada.

This R1009 road joins the Southeast route 404 which serves the northern part of the Canadian National Railway.

Its southwestern part is connected to Tourigny Lake thanks to a short strait formed by the narrowing of the banks.

Lake Tessier is mainly fed by the Faucher River which empties on its west shore (southern part of Lake Tessier) in a bay which has a length in the North-South direction of 2.9 kilometres (1.8 mi); this bay is bordered on the west by a peninsula stretching to the south.

The toponym "Lac Tessier" was formalized on December 5, 1968, by the Commission de toponymie du Québec, when it was created.
