Sitting Bull also nicknamed Slon-he or "Slow"; (c. 1831 – December 15, 1890) was a Hunkpapa Lakota Sioux holy man who led his people as a tribal chief during years of resistance to United States government policies. Born near the Grand River in Dakota Territory, he was killed by Indian agency police on the Standing Rock Indian Reservation during an attempt to arrest him and prevent him from supporting the Ghost Dance movement.

Sitting Bull's premonition of defeating the cavalry became reality. Seven months after the battle, Sitting Bull and his group left the United States to Wood Mountain, Saskatchewan, where he remained until 1881, at which time he surrendered to US forces. A small remnant of his band under Chief Waŋblí Ǧí decided to stay at Wood Mountain. After his return to the United States, he briefly toured as a performer in Buffalo Bill Cody's Wild West Show, earning $50 a week.

After working as a performer, Sitting Bull returned to the Standing Rock Agency in South Dakota. Because of fears that he would use his influence to support the Ghost Dance movement, Indian Service agent James McLaughlin at Fort Yates ordered his arrest. During an ensuing struggle between Sitting Bull's followers and the agency police, Sitting Bull was shot in the side and head by Standing Rock policemen, Lieutenant Bull Head (Tatankapah) and Red Tomahawk Marcelus Chankpidutah, after the police were fired upon by Sitting Bull's supporters. His body was taken to nearby Fort Yates for burial, but in 1953, his remains were possibly exhumed and reburied near Mobridge, South Dakota, by his Lakota family who wanted his body to be nearer to his birthplace. However, some Sioux and historians dispute this claim and believe that any remains that were moved were not those of Sitting Bull.
