John de Ufford[a] (died 20 May 1349) was chancellor and head of the royal administration to Edward III as well as being appointed to the Archbishopric of Canterbury.

[1] De Ufford was sent, along with Nicholas de Luna and Hugh Neville to Avignon in the summer of 1344 as envoys to a council held by Pope Clement VI to mediate peace during the Peace of Malestroit (January 1343 – September 1346), a breathing space for both sides during the Hundred Years War.

[4] After the death of Archbishop John de Stratford, Edward chose de Ufford as Archbishop of Canterbury, though the canons of the chapter had elected Thomas Bradwardine, the king's trusted confessor, a great intellectual and diplomat.

De Ufford was appointed to the see of Canterbury by papal bull dated 24 September 1348 and was granted the temporalities of the see on 14 December 1348.

[6] Any developing contention between the chapter and the king was rendered a dead issue when de Ufford, already aged and infirm, was carried off by the Black Death, before being consecrated, on 20 May 1349.
