The Roberge Lake is located in the unorganized territory of Lac-Masketsi, Quebec, the Mekinac Regional County Municipality, in Mauricie, in Quebec, in Canada.

This lake whose surface is usually frozen from November to April is located entirely in forest land.

A strip of land (in the north-south axis) whose width varies between 0.7 km and 1.6 km, with mountains, separates the lake and Roberge Lake Masketsi which is located west of the first.

North of these lakes, we encounter the dividing line between the water catchment areas of the Saint-Maurice River and Batiscan River.

The name "Lake Roberge" was officially registered on December 5, 1968 in the Bank of place names of the Commission de toponymie du Québec (Geographical Names Board of Québec)[1]
