Edmund Kyrton or Kirton was Abbot of Westminster from 1440 until his resignation in 1462. He is buried beneath a now lost brass in St Andrew's chapel Westminster Abbey. The brass was originally on a raised altar tomb and survived until the 18th century. It showed the abbot in mass vestments with mitre and crozier under an elaborate canopy with two crowned eagles at his feet. William Camden, in his guide published in 1600, gives the inscription, which is translated from the Latin as:
"A peaceable pastor, a man gentle towards those under him, rests buried beneath this marble slab, Edmund Kyrton, who was sometime Abbot here over a period of twenty two yers, an honest, indeed a most honourable doctor of divinity, scion of the illustrious Cobildike famiy. He preached before Pope Martin, on account of which he received many plaudits and honours. He died 3 October year of Our Lord 1466"
The abbot gave a screen for the chapel adorned with coats of arms but this was destroyed (an illustration of it survives in the Abbey archives). He seems to have belonged to a Lincolnshire family and was possibly a son of Sir John Copledike (or Copledyke) and took his name from one of two places in the county called Kirton. He was a scholar at Oxford 1407-16 and from 1421-27 was Prior of Gloucester Hall (now Worcester college) Oxford, a place set aside for Benedictines to study. At the Abbey he held various posts including treasurer and sacrist before becoming abbot..
