Billy Clanton (1862 – October 26, 1881) was a rancher in Cochise County, Arizona Territory. Billy worked with his father Old Man Clanton and his brother Ike Clanton on their ranch and stole livestock from Mexico and later U.S. ranchers. He was a member of group of outlaws that had ongoing conflicts with lawmen Wyatt, Virgil, and Morgan Earp. The Clantons repeatedly threatened the Earps because they interfered with the Cowboy's illegal activities. On October 26, 1881, Billy, Tom McLaury, and Frank McLaury were killed in the Gunfight at the O.K. Corral in the boomtown of Tombstone, Arizona Territory. The shoot out was his only gunfight.
