The Western Dakota are the Yankton, and the Yanktonai ("Iháŋktȟuŋwaŋ" and "Iháŋktȟuŋwaŋna"; "Village-at-the-end" and "Little village-at-the-end"), who reside in the Upper Missouri River area. The Yankton-Yanktonai are collectively also referred to by the endonym "Wičhíyena" (″Those Who Speak Like Men″). They also have distinct federally recognized tribes. In the past the Western Dakota have been erroneously classified as Nakota, a branch of the Sioux who moved further west. The latter are now located in Montana and across the border in Canada, where they are known as Stoney.
