Have Gun – Will Travel is an American Western series that was produced and originally broadcast by CBS on both television and radio from 1957 through 1963. The television version of the series starring Richard Boone was rated number three or number four in the Nielsen ratings every year of its first four seasons, and it is one of the few shows in television history to spawn a successful radio version. That radio series starring John Dehner debuted November 23, 1958, more than a year after the premiere of its televised counterpart.
