Roger de Bailleul (French: [ʁɔʒe də bajøl]; died 25 September 1179) was a medieval Benedictine monk, abbot of Bec, and archbishop-elect of Canterbury.
[2][3] Roger became a monk of the Abbey of Our Lady of Bec, Normandy and skilful jurist, teaching civil and canon law in England.
[2][3] As a supporter of the Empress Matilda against Stephen of Blois in the succession to the throne of England, he attracted royal opposition, and had to return to the abbey in Normandy.
[2][3] Roger also had a hospital built, which included one of the rooms for travellers, renovated the dormitory, and dug canals to carry water from two sources to the monastic apartments.
[2][3] With the other bishops and abbots of Normandy, Roger attended the ceremony at Avranches of the absolution of King Henry II for the murder of Thomas Becket.
