Robert Waldby (died 1397) was a native ofYork andfriar of theOrder of Saint Augustine who followedEdward, the Black Prince intoAquitaine, and undertook a number ofdiplomatic missions on his behalf. After studying atToulouse, he became professor of theology there. He later became close to Edward's son, KingRichard II. He was a firm opponent ofJohn Wycliffe, wrote a book denouncing him, and was a member of the Synod which assembled at Oxford in 1382 to judge his orthodoxy.

There is a possibility that Waldby wasBishop of Sodor and Man in 1381, although at the timeJohn Dongan was the bishop from 1374 to 1391. He definitely becameBishop of Aire inGascony in 1387, and Chancellor ofAquitaine, and translated to thearchbishopric of Dublin in Ireland on 14 November 1390, with the strong support of King Richard.^[1] He received thetemporalities of the See in July 1391. He was given money and troops to defendLeinster, the one province under more or less secure English rule, against hostile Irish clans, and succeeded in relievingNaas,County Kildare. He was apparently most unhappy in Ireland, and was even prepared to accept a junior English bishopric in order to come home. After five years in Dublin, he translated to thebishopric of Chichester in England on 25 October 1395,^[2] and finally becameArchbishop of York on 5 October 1396.^[3]

Waldby died on 29 December 1397 with his bishopric beingsede vacante on 6 January 1398.^[3][4] He was buried in the Chapel of St. Edmund inWestminster Abbey, where hismonumental brass still remains.^[5][6]
