William of St. Barbara or William of Ste Barbe (died 1152) was a medieval Bishop of Durham. From William's name, it is presumed that he was a native of Sainte-Barbe-en-Auge in Calvados in Normandy. He was a canon of York Minster in 1128. He was Dean of York by December of 1138. William was elected to the see of Durham on 14 March 1143 and consecrated on 20 June 1143. He was elected in opposition to William Cumin who had been intruded into the see by King David I of Scotland in 1141. Cumin was never consecrated and by 1143 had been excommunicated by Pope Innocent II who also ordered a new election to be held at York Minster. It was this election which selected William of St. Barbara. However, the new bishop was not able to enter Durham right away, and he was enthroned either on 18 October 1144 or shortly thereafter.
