The Sioux ( /ˈsuː/) are Native American and First Nations people in North America. The term can refer to any ethnic group within the Great Sioux Nation or any of the nation's many language dialects. The Sioux comprise three major divisions based on Siouan dialect and subculture: Isáŋyathi or Isáŋathi ("Knife," originating from the name of a lake in present-day Minnesota), residing in the extreme east of the Dakotas, Minnesota and northern Iowa, and are often referred to as the Santee or Eastern Dakota; Iháŋktȟuŋwaŋ and Iháŋktȟuŋwaŋna ("Village-at-the-end" and "little village-at-the-end"), residing in the Minnesota River area, they are considered to be the middle Sioux, and are often referred to as the Yankton and the Yanktonai, or, collectively, as the Wičhíyena (endonym) or the Western Dakota (and have been erroneously classified as “Nakota”); Thítȟuŋwaŋ or Teton (uncertain, perhaps "Dwellers on the Prairie"; this name is archaic among the natives, who prefer to call themselves Lakȟóta), the westernmost Sioux, known for their hunting and warrior culture, are often referred to as the Lakota.
Today, the Sioux maintain many separate tribal governments scattered across several reservations, communities, and reserves in the Dakotas, Nebraska, Minnesota, and Montana in the United States; and Manitoba and southern Saskatchewan in Canada.
