Faillon Lake is a freshwater body of the townships of Faillon (northeastern part) and Boisseau (southwestern part), in the territory of Senneterre, in La Vallée-de-l'Or Regional County Municipality (RCM), in the administrative region of Abitibi-Témiscamingue, in the province of Quebec, in Canada.
Lake Faillon is crossed to the Southwest by the current of the Mégiscane River.
Forestry is the main economic activity of the sector; recreational tourism activities come second. Its surface is generally frozen from the beginning of December to the end of April.
The hydrographic slope of Lake Faillon is mainly served by a forest road that goes north-east on the north bank of the Mégiscane River. The southwestern part of the lake is served by another branch of the forest road that runs east.
