Hairy Moccasin (also known as Esh-sup-pee-me-shish) (c. 1854 – October 9, 1922) was a Crow scout for George Armstrong Custer's 7th Cavalry during the 1876 campaign against the Sioux and Northern Cheyenne.

[1] He volunteered to become an Army scout on April 10, 1876, and joined fellow Crow warriors White Man Runs Him, Curly, Goes Ahead, White Swan, and Half Yellow Face (leader of the Crow scouts) in the valley of the Little Big Horn River near the current site of Crow Agency, Montana to assist the Army's fight against the Sioux and Northern Cheyenne.

He joined Strikes the Bear (an Arikara Scout), White Man Runs Him, and Goes Ahead with Major Marcus Reno's column on the ridge overlooking the last stand.

[2] After the Black Hills War ended, Hairy Moccasin settled onto the Crow Reservation in Montana.

He died October 9, 1922, near Lodge Grass and was buried in Saint Ann's Cemetery.
