Hairy Moccasin (Esh-sup-pee-me-shish) (died October 9, 1922 near Lodge Grass, Montana) was a Crow scout for George Armstrong Custer’s Seventh Cavalry during the 1876 campaign against the Sioux and Northern Cheyenne. He was an survivor of the Battle of the Little Big Horn.

He volunteered to become an Army scount on April 10, 1876 and joined fellow Crow warriors White Man Runs Him, Curley, Goes Ahead and several others to assist the Army's fight against the Sioux and Northern Cheyenne. Both tribes were traditional enemies of the Crow.

After scouting the encampment on the banks of the Little Big Horn River, they reported to Custer. After Custer refused their advice to wait for reinforcements, Hairy Moccasin was dismissed by Custer about an hour before the last stand. He joined Strikes the Bear , White Man Runs Him, and Goes Ahead with Major Marcus Reno column on the ridge overlooking the last stand. Attacked but not overrun, Marcus’s column survived the engagement.

After the plains wars ended, Hairy Moccasin settled onto the Crow reservation in Montana. He died their in 1922 and was buried in Saint Ann's Cemetery in Lodge Grass, Montana.
