Michel Seydoux (born 11 September 1947) is a French businessman and film producer. He also serves as the president and chairman of the French association football club Lille OSC.

In 1975-1976, Seydoux worked with director Alejandro Jodorowsky on a film adaptation of Frank Herbert's Dune. The movie was never made due to lack of financing; the story of the project is told in Jodorowsky's Dune, which prominently features Seydoux.
