Joseph Isaac "Ike" Clanton (1847 – June 1, 1887) was a member of a loosely associated group of outlaws known as the The Cowboys that had ongoing conflicts with lawmen Wyatt, Virgil and Morgan Earp as well as Doc Holliday. On October 26, 1881, Ike was present at the Gunfight at the O.K. Corral in the boomtown of Tombstone, Arizona Territory, but was unarmed and ran from the gunfight, in which his 19-year-old brother, Billy, was killed.
