Eskimo (/ˈɛskɪmoʊ/ ESS-kih-moh) or Eskimos are the indigenous circumpolar peoples who have traditionally inhabited the northern circumpolar region from eastern Siberia (Russia) to Alaska (United States), Northern Canada, Nunavik, Nunatsiavut, and Greenland. The two main peoples known as Eskimo are the Inuit (including the Alaskan Iñupiat, the Greenlandic Inuit, and the Inuit peoples of Canada) and the Yupik (or "Yuit") of eastern Siberia and Alaska. A third northern group, the Aleut, are closely related to both. They share a relatively recent common ancestor and a language group, Eskimo-Aleut.
