Warren Baxter Earp (March 9, 1855 – July 6, 1900) was the youngest brother of Wyatt, Morgan, Virgil, James, and Newton Earp. Although he was not present during the Gunfight at the O.K. Corral, after Virgil was maimed in an ambush, Warren joined Wyatt and was in town when Morgan was assassinated. He also helped Wyatt in the hunt for the outlaws they believed responsible. Later in life, Warren developed a reputation as a bully and was killed in an argument in 1900.
