Ignace Lepp (October 26, 1908, Orajõe, Pärnu county, Estonia – May 29, 1966), born John Robert Lepp, was a French writer. The son of a naval captain, he was actually born aboard a ship in the Baltic Sea where he was brought up by his mother together with his brother until he was five years old. At the age of 15, he joined the French communist party after reading Maxim Gorki's The Mother, a novel which made a lasting impression on him and led him to abandon individualism as he himself recalls in his autobiography From Marx to Christ.
