Mark Gertler (9 December 1891 – 23 June 1939), born Marks Gertler, was a British painter of figure subjects, portraits and still-life. His early life and his relationship with Dora Carrington were the inspiration for Gilbert Cannan's novel Mendel. The characters of Loerke in D. H. Lawrence's Women in Love, and Gombauld in Aldous Huxley's Crome Yellow were based on him.
