Pawnee Killer (born 1826) was a leader of the Oglala Sioux. He also led a band of mixed Sioux-Cheyenne Dog Soldiers during the US war against the Plains Indians. His name was derived from his exploits against the Pawnee, the traditional enemies of the Oglala and allies of the US government. He participated in the attack on Julesburg in Colorado and the Fetterman Fight in Wyoming during Red Cloud's War. He also fought in the so-called Kidder fight in Kansas in 1867 and possibly the Battle of Beecher Island in 1868.
