The Lac au Goéland (English: Gull Lake) is a freshwater body of water crossed by the Waswanipi River and is located within Eeyou Istchee James Bay (municipality), within the administrative region of Nord-du-Québec, in the province of Quebec, in Canada.

The surface of Goéland Lake is usually frozen from early November to mid-May, however, safe ice movement is generally from mid-November to mid-April.

The Max Passage is the length of 10.5 kilometres (6.5 mi) and connects the Lake Maicasagi, located to the Northeast.

Father Vaillancourt used the spelling Ch¯ - y¯asK, meaning "gull" because the islands served as refuges to several colonies of this bird swimmer and omnivore.

[2] The toponym "Lac au Goéland" was formalized on December 5, 1968, by the Commission de toponymie du Québec, when it was created.
