William James Durant (/dəˈrænt/; November 5, 1885 – November 7, 1981) was an American writer, historian, and philosopher. He is best known for The Story of Civilization, 11 volumes written in collaboration with his wife Ariel Durant and published between 1935 and 1975. He was earlier noted for The Story of Philosophy (1924), described as "a groundbreaking work that helped to popularize philosophy".

He conceived of philosophy as total perspective, or, seeing things sub specie totius, a phrase inspired by Spinoza's sub specie aeternitatis. He sought to unify and humanize the great body of historical knowledge, which had grown voluminous and become fragmented into esoteric specialties, and to vitalize it for contemporary application.

Will and Ariel Durant were awarded the Pulitzer Prize for General Non-Fiction in 1968 and the Presidential Medal of Freedom in 1977.
