Edmée Elizabeth Monica Dashwood, née de la Pasture (9 June 1890 – 2 December 1943), commonly known as E. M. Delafield, was a prolific English author who is best-known for her largely autobiographical Diary of a Provincial Lady, which took the form of a journal of the life of an upper-middle class Englishwoman living mostly in a Devon village of the 1930s, and its sequels in which the Provincial Lady buys a flat in London and travels to America. Other sequels of note are her experiences looking for war-work during the Phoney War in 1939, and her experiences as a tourist in the Soviet Union.

Daughter of the novelist Mrs. Henry De La Pasture.
