Saint-Cyr Lake /ˌseɪntˈsɪər/ is a freshwater body of water crossed by the Saint-Cyr River South in the north-eastern part 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.
This body of water extends in the townships of Mesplet and Cherrier. Forestry is the main economic activity of the sector. Recreational tourism activities come second.

The surface of Lac Saint-Cyr is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.
