Michael Marshall (September 13, 1944 – June 2, 2005) was a French American actor.

Marshall was born in Cedars-Sinai Medical Center, a hospital in Hollywood, on September 13, 1944. He was the only child of American actor-director William Marshall and French actress Michèle Morgan and was the stepson of Gérard Oury as well as half-brother to Tonie Marshall.

When his parents divorced, his father made sure that he received an American education. He began studying law, but dreamed of becoming an actor.

He later joined his mother in Paris. Marshall began to take drama classes from Raymond Griard and later directed his first film, Potato, in France under the direction of Robert Thomas, adapted from the play's eponymous Marcel Achard. He had already appeared in two films from overseas, the first was directed by his father, and the second by Vincente Minnelli. Gérard Oury, Marshall's step-father, offered him a role of a young Canadian airman in La Grande Vadrouille, as a doctor in Le Coup du parapluie.

Marshall had a long, low-key career as a character actor in French cinema. On stage he starred in Croque-monsieur, Le Vallon, and Point de feu sans fumée. Marshall has also appeared in several television series and featured in the pre-credit sequence of Moonraker (1979) filmed in France.
