The Sihásapa or Blackfoot Sioux are a division of the Lakota people, Titonwan, or Teton.

Sihásapa is the Lakota word for "Blackfoot", whereas Siksiká has the same meaning in the Nitsitapi language, and, together with the Kainah and the Piikani forms the Nitsitapi Confederacy. As a result, the Sihásapa have the same English name as the Blackfoot Confederacy (correctly: Nitsitapi Confederacy), and the nations are sometimes confused with one another.

The Sihásapa lived in the western Dakotas on the Great Plains, and consequently are among the Plains Indians. Their official residence today is the Standing Rock Reservation^[1] in North and South Dakota and the Cheyenne River Reservation in South Dakota, home also to the Itazipco (No Bows), the Minneconjou (People Who Live Near Water) and Oohenumpa (Two Kettle), all bands of the Lakota.
