The lac aux Écorces (English: bark lake) is a freshwater body crossed by the Rivière aux Écorces, in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province from Quebec, to Canada.

Lac aux Écorces is part of the Laurentides Wildlife Reserve.

Some secondary forest roads serve this area for forestry and recreational tourism activities.

The surface of Lac aux Écorces is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally from mid-December to mid-March.
