William Marmion, Baron Marmion of Torrington was an English clergyman and member of Simon de Montfort's Parliament.

He was the son of Robert Marmion, 3rd Baron Marmion of Tamworth and his second wife Philippa.

During the First Barons' War a group of rebellious barons, supported by Prince Louis of France, made war on King John of England due to his cruel and inept leadership. Although John signed the Magna Carta on 15 June 1215 war broke out in England. William Marmion's elder brother, Robert Marmion the elder, was one of the rebel barons (as was their father) and on 25 February 1216 the King sent William to see if he could persuade him to make peace with the King again. John died on 18 October 1216 and was succeeded by his nine-year-old son Henry who, not being despised by the barons, attempted to calm things down.

On 15 May 1218 Henry confirmed William's lordship of the manor of Torrington, Lincolnshire and 10 librates (£10 worth of land) in Berwick, Sussex which his father had previously given him by charter.

Distrust between the barons and Henry remained though and in 1222 the king ordered the Sheriff of Lincolnshire to seize the lands of William Marmion, Cleric, at Torrington and to value them, as Henry had been informed that William had left England without licence to join his rival King Louis. It was not until December 1235 that William reappeared and petitioned the king to give him back his lands, claiming that he not been in France at all. William was forgiven and reunited with Torrington after making a payment of £20.

William was presented to the church of Coningsby c. 1236 and acted as guardian to his nephew Philip Marmion, 5th Baron Marmion of Tamworth during his minority. According to Palmer, William later became Dean of the collegiate church of Tamworth.
