Edward Capehart O'Kelley (October 1, 1857 – January 13, 1904) was the man who murdered Robert Ford, who had killed the famous outlaw Jesse James to receive a bounty. He was the subject of a 1994 book, Ed O'Kelley: The Man Who Killed Jesse James' Murderer, by Judith Ries, O'Kelley's great-great-niece.
Over the years, historians and contemporary newspapers variously spelled O'Kelley's surname as "Kelly" or "O'Kelly", sometimes mistakenly using the letter "O" as his middle initial.
