William Exmew was an English Carthusian monk and priest who lived during the early 16th century. A scholar educated at Christ's College, Cambridge, he was highly regarded for his knowledge of Latin and Greek. He served in various leadership roles at the London Charterhouse, including as procurator. Because of his refusal to acknowledge the king as the head of the Church, he was arrested and eventually executed at Tyburn in 1535 during the religious shifts in England.
