Ernulf (1040– 15 March 1124) was a French Benedictine monk who became prior of Christ Church in Canterbury, abbot of Peterborough, and bishop of Rochester in England. A jurist and an architect as well, he was responsible for greatly expanding Canterbury Cathedral during his time there.

Ernulf studied under Lanfranc at the monastery of Bec, entered the Benedictine Order, and lived at the monastery of St-Lucien, Beauvais. At the suggestion of Lanfranc, he went to England some time after 1070 and joined the monks of Canterbury. He studied under Ivo of Chartres and was considered an expert on canon law.

Ernulf was made prior by Archbishop Anselm in 1096 and began the expansion of Lanfranc's rebuilt Canterbury Cathedral, taking down the eastern part of the church which Lanfranc had built and erecting a far more magnificent structure. This included the famous crypt (Our Lady of the Undercroft), as far as Trinity Tower. The chancel was finished by his successor Conrad. The chapel of St. Andrew is also part of Ernulf's work. In 1107, he was made Abbot of Peterborough, where he was one of the teachers of Hugh Candidus. On 28 September 1114, he was invested as bishop of Rochester by Ralph d'Escures, the archbishop of Canterbury. He was consecrated on 26 December 1115. At Peterborough and Rochester, Ernulf had the old buildings torn down and erected new dormitories, refectories, chapter houses, etc.
