Muriel Draper (c. 1886 - August 26, 1952) was an American writer, artist and social activist. Moving in English and American art circles, she participated prominently in the Harlem Renaissance. A follower of Russian mystic G. I. Gurdjieff, she collaborated with other of his followers, such as poet Jean Toomer. In 1929 she published her major work Music at Midnight, for which she became widely known.
After a trip to the Soviet Union in 1934, she became active in left wing politics. She also visited Spain during the Civil War and later raised funds for the loyalists in New York.
