Arthur Bernard Cook (22 October 1868, Hampstead – 26 April 1952, Cambridge) was a British classical scholar, known for work in archaeology and the history of religions. He is best known for his three-part work Zeus: A Study in Ancient Religion. Cook is often considered one of the Cambridge Ritualists, and although he did not produce theoretical works, he has been called "perhaps the most typical disciple" of J. G. Frazer. His poem Windsor Castle won the Chancellor's Gold Medal for poetry at Cambridge.
