The Wackiest Ship in the Army is an American comedy series that aired for one season on NBC between September 19, 1965, and April 17, 1966. Produced by Harry Ackerman and Herbert Hirschman, the series is loosely based on the 1960 film starring Jack Lemmon and Ricky Nelson.

Lieutenant Rip Crandall is hoodwinked into taking command of the "Wackiest Ship in the Navy" – a real garbage scow with a crew of misfits who don't know a jib from a jigger. What none of them knows, including Crandall, is that this ship has a very important top-secret mission to complete in waters patrolled by the Japanese fleet. Their mission will save hundreds of allied lives – if only they can get there in one piece.
