The Bourgeois Lake is a freshwater body located in the north central part of the Gouin Reservoir, in the territory of the town of La Tuque, in the administrative region of the Mauricie, in the province of Quebec, in Canada.

The De la Rencontre Creek, coming from the North, flows into the Male Lake, almost at the north-west entrance of Lac Bourgeois.

A peninsula stretching northward on 16.4 kilometres (10.2 mi) distinguishes the eastern side of Plamondon Bay and Lake Bourgeois; another peninsula stretching southward on 10.1 kilometres (6.3 mi) distinguishes the east side of the De la Rencontre Creek and Bourgeois Bay.

These two peninsulas meet almost, forming a narrow passage where all the water of the western part of the Gouin Reservoir passes towards Kanatakompeak Bay (towards the East).

The toponym "Lac Bourgeois" was formalized on December 18, 1986, by the Commission de toponymie du Québec[2] .
