La Petite Rivière is a tributary of the Gulf of St. Lawrence, flowing in the municipality of L'Île-d'Anticosti, in the Minganie Regional County Municipality, in the administrative region of Côte-Nord, in province of Quebec, in Canada.
The main forest road (east–west direction) of Anticosti Island serves the upper part of this valley; it passes between the Lake of the Fourteenth Mile and Lake Simonne. The intermediate part of this valley is served by a forest road (direction es-west). Along the coast, the forest road connects to the east with the forest road network for forestry purposes.
Forestry is the main economic activity in this area; recreational tourism activities, second.
