John Robert "Battleship" Kelly (born June 6, 1946) is a Canadian retired professional ice hockey player who played 425 games in the National Hockey League. He played for the St. Louis Blues, Pittsburgh Penguins, and Chicago Black Hawks. Although official NHL records call him "Bob Kelly" he was commonly known during his NHL playing career as J. Bob Kelly, in an effort to differentiate himself from the Bob Kelly who played primarily with the Philadelphia Flyers at that time.
