Eskimo (/ˈɛskɪmoʊ/) is an exonym used to refer to two closely related Indigenous peoples: the Inuit (including the Alaska Native Iñupiat, the Greenlandic Inuit, and the Canadian Inuit) and the Yupik (or Yuit) of eastern Siberia and Alaska. A related third group, the Aleut, which inhabit the Aleutian Islands, are generally excluded from the definition of Eskimo. The three groups share a relatively recent common ancestor, and speak related languages belonging to the Eskimo–Aleut language family.
