Lac-Fouillac (French pronunciation: [lak fujak]) is a former unorganized territory in the Abitibi-Témiscamingue region of Quebec, Canada, now part the Municipality of Rivière-Héva in the La Vallée-de-l'Or Regional County Municipality.

In July 2007, the residents of Lac-Fouillac overwhelmingly rejected the amalgamation of their territory with the City of Malartic.

96% of voters voted against annexation in a referendum.

But two years later on August 29, 2009, Lac-Fouillac, together with the western portion of the Unorganized Territory of Lac-Granet, was merged into the Municipality of Rivière-Héva.
