William de Corbeil or William of Corbeil (c. 1070 – 21 November 1136) was a medieval Archbishop of Canterbury. Very little is known of William's early life or his family, except that he was born at Corbeil, south-east of Paris, and that he had two brothers. Educated as a theologian, he taught briefly before serving the bishops of Durham and London as a clerk and subsequently becoming an Augustinian canon. William was elected to the See of Canterbury as a compromise candidate in 1123, the first canon to become an English archbishop. He succeeded Ralph d'Escures who had employed him as a chaplain.

Throughout his archbishopric, William was embroiled in a dispute with Thurstan, the Archbishop of York, over the primacy of Canterbury. As a temporary solution, Pope Honorius II appointed William the papal legate for England, giving him powers superior to those of York. William concerned himself with the morals of the clergy, and presided over three legatine councils, which among other things condemned the purchase of benefices or priesthoods, and admonished the clergy to live a celibate life. He was also known as a builder; among his constructions is the keep of Rochester Castle. Towards the end of his life William was instrumental in the selection of Count Stephen of Boulogne as King of England, despite his oath to the dying King Henry I that he would support the succession of his daughter, the Empress Matilda. Although some chroniclers considered him a perjurer and a traitor for crowning Stephen, none doubted his piety.
