John de Bohun, 5th Earl of Hereford (23 November 1306 – 20 January 1336) was born in St Clement's, Oxford to Humphrey de Bohun, 4th Earl of Hereford and Elizabeth of Rhuddlan, a daughter of Edward I of England. After his father's death at the Battle of Boroughbridge, the family lands were forfeited. It was not until after the fall of the Despensers that John was permitted to succeed to his inherited position as Earl of Hereford and Essex and hereditary Constable of England. He did not play much of a public role, despite his high titles and offices, most likely because he had some sort of incapacity.[1] His younger brothers were often deputed to fulfill his duties as Constable. He was buried in Stratford Langthorne Abbey, London.
