Jean Mamy (8 July 1912, Chambéry, Savoie - 29 March 1949, Arcueil) was a French actor, producer, film and theatre director, screenwriter and journalist, notable for his collaboration with the Vichy regime (for which he was shot in 1949). He was also known by the pseudonym Paul Riche, and wrote for L'Appel. He belonged to the inter-war left and was film editor on Jean Renoir's 1931 On purge bébé, but on the fall of France he decided on collaboration.
