The Inuit (pronounced or ; Inuktitut: , "the people") are a group of culturally similar indigenous peoples inhabiting the Arctic regions of Greenland, Canada and Alaska. Inuit is a plural noun; the singular is Inuk. The Inuit languages are part of the Eskimo-Aleut family. Inuit Sign Language is a critically endangered language isolate spoken in Nunavut. 

In the United States and Canada, the term "Eskimo" was commonly used to describe the Inuit and Alaska's Yupik and Iñupiat peoples. However, "Inuit" is not accepted as a term for the Yupik, and "Eskimo" is the only term that includes Yupik, Iñupiat and Inuit. However, aboriginal peoples in Canada and Greenlandic Inuit view "Eskimo" as pejorative, and "Inuit" is more commonly used in self-reference for these groups. In Canada, sections 25 and 35 of the Constitution Act of 1982 classified the Inuit as a distinctive group of Aboriginal Canadians who are not included under either the First Nations or the Métis. 

The Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, Nunatsiavut and NunatuKavut in Labrador, and in various parts of the Northwest Territories, particularly around the Arctic Ocean. These areas are known in Inuktitut as the "Inuit Nunangat".
