Thomas of Bayeux (died 18 November 1100) was Archbishop of York from 1070 until 1100. He was educated at Liège and became a royal chaplain to Duke William of Normandy, who later became King William I of England. After the Norman Conquest, the king nominated Thomas to succeed Ealdred as Archbishop of York. After Thomas' election, Lanfranc, Archbishop of Canterbury, demanded an oath from Thomas to obey him and any future Archbishops of Canterbury; this was part of Lanfranc's claim that Canterbury was the primary bishopric, and its holder the head of the English Church. Thomas countered that York had never made such an oath. As a result, Lanfranc refused to consecrate him. The King eventually persuaded Thomas to submit, but Thomas and Lanfranc continued to clash over ecclesiastical issues, including the primacy of Canterbury, which dioceses belonged to the province of York, and the question of how York's obedience to Canterbury would be expressed.

After King William I's death Thomas served his successor, William II, and helped to put down a rebellion led by Thomas' old mentor Odo of Bayeux. Thomas also attended the trial for rebellion of the Bishop of Durham, William de St-Calais, Thomas' sole suffragan, or bishop subordinate to York. During William II's reign Thomas once more became involved in the dispute with Canterbury over the primacy when he refused to consecrate the new Archbishop of Canterbury, Anselm, if Anselm was named the Primate of England in the consecration service. After William II's sudden death in 1100, Thomas arrived too late to crown King Henry I, and died soon after the coronation.
