Theulf (died 20 October 1123) was a medieval Bishop of Worcester.

Theulf was a canon of Bayeux Cathedral and a king's chaplain^[1] before he was nominated to the see of Worcester on 28 December 1113. The archbishopric of Canterbury was then vacant and his consecration as bishop was delayed until 27 June 1115 when Archbishop Ralph d'Escures received his pallium from Rome and was thus empowered to perform the ceremony. Theulf died on 20 October 1123.^[2] The medieval chronicler William of Malmesbury claimed that Theulf confessed on his deathbed that he had purchased his bishopric.^[3]
