The Lake Édouard (French pronunciation: [lak edwaʁ]) is a lake in Canada, in province of Quebec, in the municipality of Lac-Édouard in the administrative region of Mauricie.

The entire area of this lake is located in the municipality of Lac-Édouard.

The lake's name is also attested in Montagnais language as "Etoolsakigan", which also means "Lac Édouard".

The loggers were active on the lake to transport timber to the sawmill with pulling boats with cables surrounding floating logs.
