Marie-Paul Achille Auguste Le Flem (18 March 1881 – 31 July 1984) was a French composer and music critic.

Born in Radon, Orne, of Breton parentage, and living most of his life in Lézardrieux, Le Flem studied at the Schola Cantorum under Vincent d'Indy and Albert Roussel, later teaching at the same establishment, where his pupils included Erik Satie (as a mature student) and André Jolivet.

Before World War I, Le Flem produced several major works, including his First Symphony, a Fantasy for Piano and Orchestra, and an opera.

Three additional symphonies and a second opera followed before he was finally forced to give up composition in 1976, at the age of 95, due to blindness.

Le Flem also composed the music for Jean Tedesco's short film The Great Gardener of France in 1942.
