John de Egglescliffe (died 1347) was a 14th-century Englishbishop. Little is known of his personal background except that he was anAugustinian friar, and that he probably came fromCounty Durham (there is a parish calledEgglescliffe there).

In early 1317,Stephen de Donydouer was elected by thecanons of thesee ofGlasgow asbishop of Glasgow. After election, Stephen travelled to theHoly See to receive consecration, but the pope,Pope John XXII rejected his election under pressure from KingEdward II of England. A letter dated 13 July 1317 was sent by King Edward thanking the pope for refusing to accept the election. On 18 August, the pope had learned of Stephen's death, and announced that he would appoint a bishop himself.

The pope instructedNicholas Alberti,Bishop of Ostia, to appoint and consecrate the English papal penitentiary John de Ecclescliffe to the bishopric of Glasgow. This went ahead atAvignon at some point before 17 July 1318. Meanwhile, ignorant of the pope's reservation, the Glasgow canons electedJohn de Lindesay. As an Egglescliffe was regarded as a pro-English appointee, Egglescliffe never took possession of this see. However, John was given another see to take charge, as in March 1323 he was translated to thebishopric of Connor. This did not last long though, as he was soon translated again, this time to thebishopric of Llandaff on 20 June 1323, i.e., just three months after becoming bishop of Connor. He remained Bishop ofLlandaff for twenty-four years, and died in 1347.
