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 by 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.
