Ormonde Maddock Dalton, FBA (1866–1945) was a British museum curator and archaeologist. Though very much an all-rounder, his main expertise was in medieval art. He usually published as O. M. Dalton, but also wrote under the pseudonym W. Compton Leith.
From 1921 to 1928 he was Keeper of the British and Medieval Antiquities Department at the British Museum. As well as the books below, he wrote a stream of articles and short books for the museum.
