The Whistler describes at least one artist and a number of versions of a radio drama.

1. The Whistler is an American radio mystery drama which ran from May 16, 1942 until September 22, 1955 on the west-coast regional CBS radio network. The show was also broadcast in Chicago and over Armed Forces Radio. On the west coast, it was sponsored by the Signal Oil Company: "That whistle is your signal for the Signal Oil program, The Whistler." There were also two short-lived attempts to form east-coast broadcast spurs: July 3 to September 25, 1946, sponsored by the Campbell Soup Company; and March 26, 1947 to September 29, 1948, sponsored by Household Finance. The program was also adapted into a film noir series by Columbia Pictures in 1944.

2. The Whistler is an Irish YouTube-based instrumentalist, from Cork. He plays traditional and new tin-whistle tunes and songs for an international audience; usually unaccompanied.
