Weenusk First Nation (Cree: ᐐᓈᐢᑯ ᐃᓂᓂᐗᐠ|italic=no (Cree: wînâsko ininiwak); unpointed: ᐧᐃᓇᐢᑯ ᐃᓂᓂᐧᐊᐠ) is a Cree First Nation band government in the Canadian province of Ontario. In September, 2007, its total registered population was 516. Weenusk First Nation was an independent member of the Nishnawbe Aski Nation (NAN) but now have joined the Mushkegowuk Council, a regional tribal council, who is also a member of NAN.
Weenusk First Nation's reserve is the 5310 ha Winisk Indian Reserve 90. Associated with the reserve is their Winisk Indian Settlement also known as Peawanuck, which also holds reserve status. Originally, the Weenusk First Nation was located within their reserve, but they were forced to move 30km (20miles) southwest to Peawanuck when on May 16, 1986, spring floods swept away much of the original settlement, which had been located 6km (04miles) upriver from Hudson Bay.
In the Cree language, "Peawanuck" means "a place where flint is found," while "Weenusk" means "ground hog." The community, being primarily Swampy Cree, speaks the n-dialect of the Cree language. Being that the community is composed of Cree, Oji-cree, Ojibwa and Métis peoples, in addition to Cree, Anishininiimowin and Ojibwemowin are also spoken there.
Weenusk is governed by Chief Joey Hunter and his three councillors: Jeff Hunter, Leah Hunter, and Paul Koostachin.
