Lac à la Loutre is a freshwater body of the watershed of the rivière aux Anglais, flowing in the unorganized territory of Rivière-aux-Outardes, in the Manicouagan Regional County Municipality, in the administrative region of Côte-Nord, in the province of Quebec, in Canada.

[2] The "Lac à la Loutre" is located in the unorganized territory of Rivière-aux-Outardes, north of the city of Baie-Comeau.

This lake turns out to be the main head water body on the slope of the rivière aux Anglais.

[2] From the mouth of Lac à la Loutre, the current descends on 65 km (40 mi) generally towards the south-east, following the course of the rivière aux Anglais, in particular passing by end of segment on the north side of an industrial sector in the eastern part of Baie-Comeau, to discharge onto the west shore of Baie aux Anglais, on the north shore of the Estuary of Saint Lawrence.

The toponym "lac à la Loutre" was formalized on December 5, 1968 at the Place Names Bank of the Commission de toponymie du Québec.
