Arthur Augustus Tilley (1 December 1851 – 4 December 1942) was an academic of the University of Cambridge. An Old Etonian, his first subject at Cambridge was Classics, after which he began a career as a barrister. He returned to his old college to teach Classics, going on to specialise in French literature and becoming both a literary critic and a historian.
Tilley is remembered at Cambridge for resisting the modernisation of behaviour and dress which he observed, describing the new elements in his college as "bounders".
