Le Gros Bras (English: The Big Arm) is a tributary of the eastern bank of the lower part of the rivière du Gouffre, flowing in the unorganized territory of Lac-Pikauba and the municipality of Saint-Urbain, in the Charlevoix Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada. The upper part of this watercourse begins in Grands-Jardins National Park.

This valley is mainly served by the route 138 whose segment near the Saint-Laurent river is designated boulevard Monseigneur de Laval; then consecutively going up north rue Saint-Édouard in Saint-Urbain, chemin Saint-François entering the forest zone, then "chemin du Parc-des-Grands-Jardins" further north. Forestry is the main economic activity in this valley; recreational tourism, second.

The surface of Le Gros Bras is generally frozen from the beginning of December until the beginning of April; however, safe circulation on the ice is generally done from mid-December to the end of March. The water level of the river varies with the seasons and the precipitation; the spring flood generally occurs in April.
