We Joined the Navy is a 1962 British comedy film directed by Wendy Toye and starring Kenneth More, Lloyd Nolan, Joan O'Brien, Derek Fowlds, Graham Crowden, Esma Cannon and John Le Mesurier. Produced by Daniel M. Angel, it was based on the 1959 novel of the same name by John Winton, a former Royal Navy lieutenant commander.

The film was shot on location in Villefranche-sur-Mer, near Nice and Monaco, on board the Royal Naval College, Dartmouth, and USS Springfield as well as at ABPC Elstree Studios. The film's sets were designed by art director John Howell. It was shot in CinemaScope by cinematographer Otto Heller.

In addition to the credited cast, the film features uncredited cameos by Michael Bentine, Sidney James, Rodney Bewes and Dirk Bogarde (in a gag reference to his Doctor series role, Simon Sparrow).

Director Wendy Toye said "it was a fun film to do it really was, because it is always lovely to work with Kenny More, it always was. And Lloyd Nolan was such an excellent actor."
