Monkton House, West Dean, West Sussex is an English country house designed in 1902 by Edwin Lutyens for Willie James. It was extensively remodelled for his son, Edward James, in the 1930s. Working with Christopher Nicholson and Hugh Casson, and assisted by Salvador Dalí, James constructed what has been called "the only complete Surrealist house ever created in Britain". The collection of Surrealist art and furniture which James assembled at the house, much of it by Dalí himself, was "one of the largest and most important in the world". A private residence, Monkton is a Grade II listed building.

William Dodge James, was the son of a wealthy American merchant, who was raised and educated in England. He married Evelyn Elizabeth Forbes, daughter of the 4th Baronet of Newe, who became a celebrated society hostess of the period. James was a big game hunter and Edward, Prince of Wales, was one of the frequent visitors to their West Dean country estate in West Sussex.
