Arthur Lett-Haines (1894 – 25 February 1978), known as Lett Haines, was a British painter and sculptor who experimented in many different media, though he generally characterised himself as "an English surrealist". He was part of a London artistic circle, which included D. H. Lawrence, the Sitwells and Wyndham Lewis, but for most of his life lived with the painter and gardener Cedric Morris in Cornwall, Paris and finally Suffolk.
