Léo Joannon (21 August 1904 – 28 March 1969) was a French writer and film director. Born in Aix-en-Provence, Joannon was originally a law student who became a novelist and journalist before entering the film industry in the 1920s as a cameraman.
Joannon first attracted international attention in early 1939 during the production of S.O.S. Mediterranean, when his attempts to include shots of a German naval ship docked in the port of Tangier created a diplomatic incident between the pre-World War II French and German governments. The film later won the Grand Prix du Cinema Français.
