Hugh de Mapenor (or Hugh de Mapenore) was a medieval Bishop of Hereford.
He was the son of Robert de Mapenore and his wife Matilda, who lived in Herefordshire at Hampton, Herefordshire near Leominster. He served William de Braose as a clerk from 1189 to 1196, and then served William's son Giles de Braose, Bishop of Hereford. He occupied the office of Dean of Hereford before September 29 1202.
He was elected to the see of Hereford on February 3 1216. King John of England objected to the election, and took the case to Pope Honorius III, but the king died before the case was decided. Hugh was consecrated on December 18 1216 by Sylvester Bishop of Worcester.
He died in April of 1219, probably on the 16th.
