John de St Paul (c. 1295 – 1362), also known as John de St. Pol, John de Owston and John de Ouston, was an English-born cleric and judge of the fourteenth century. He was Archbishop of Dublin 1349–62 and Lord Chancellor of Ireland 1350–56. He had previously been Master of the Rolls in England 1337–40.[1] Apart from a brief period of disgrace in 1340, he enjoyed the confidence of King Edward III. He was described as a zealous supporter of English rule in Ireland, but also as a pragmatic statesman who was willing to conciliate the Anglo-Irish ruling class. He did much to enlarge and beautify Christ Church, Dublin, although virtually no trace of his improvements survive, as they were destroyed by the Victorian rebuilding of the cathedral. [2][3]
