Have Gun – Will Travel is an American Western television 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.

Television Westerns are programs with settings in the later half of the 19th century in the American Old West, Western Canada and Mexico during the period from about 1860 to the end of the so-called "Indian Wars". More recent entries in the Western genre have used the neo-Western subgenre, placing events in the modern day, or the space Western subgenre but still draw inspiration from the outlaw attitudes prevalent in traditional Western productions.
