Edward Capehart O'Kelley (October 1, 1857 – January 13, 1904) was an American killer who killed Robert Ford, who had killed the famous outlaw Jesse James to receive a bounty. He was the subject of a 1994 book by his (O'Kelley's) great-great-niece. Over the years, historians and contemporary newspapers erroneously spelled O'Kelley's surname as "Kelly" or "O'Kelly", sometimes mistakenly using the letter "O" as his middle initial.
