Wyndham Marmaduke P. Lloyd (1909-1997) was an English artist. Lloyd moved to Ceylon to become a tea planter at the age of 19. During the Second World War Lloyd served in North Africa with the Ceylon Planters Rifle Corps and returned to Ceylon after the war where he worked as a tea broker. In 1960, having found that he had skin cancer, Lloyd moved back to England and retired to a farm in Great Horkesley, Essex, which he had inherited from his brother.

Lloyd had little formal training in art and, apart from some night classes at Colchester, was mostly self-taught. An artist notable for his landscapes which had a strong pattern element, his first three exhibitions were held in Ceylon. He also exhibited with the New English Art Club, the Royal Institute of Painters, and the Royal Society of British Artists. A member of the Colchester Art Circle, Lloyd died in 1997.
