John of Oxford (died 2 June 1200) was a medieval Bishop of Norwich.
He was a royal clerk and represented King Henry II at a diet held in May 1165 at Würzburg that dealt with the issue of the Antipope Paschal III.
Bishop Josceline de Bohon of Salisbury appointed John Dean of Salisbury, but the appointment was overruled by Pope Alexander III on 8 June 1166 because of John's dealings with the antipope and because some of the cathedral chapter were absent from the election.
Archbishop Thomas Becket then excommunicated John on 12 June 1166, and both the chapter and the king appealed to the pope, the king sending John to Rome.
[1] John was elected to the see of Norwich on 26 November 1175 and was consecrated on 14 December 1175.
