Bishop of Kilmacduagh and Kilfenora

The Bishop and Apostolic Administrator of Kilmacduagh and Kilfenora was an episcopal title which took its name after the small villages of Kilmacduagh in County Galway and Kilfenora in County Clare, Republic of Ireland. Accurately, the title was an alternative sequence of the Bishop of Kilmacduagh and Apostolic Administrator of Kilfenora followed by the next holder as the Bishop of Kilfenora and Apostolic Administrator of Kilmacduagh.

It was decreed by Pope Benedict XIV in 1750 that the Episcopal sees of Kilmacduagh and Kilfenora were to be united. The ordinary of the united dioceses was to be alternately bishop of one diocese and apostolic administrator of the other, since the two dioceses were in different ecclesiastical provinces. The first holder of this unusual arrangement was Peter Kilkelly, who had been Bishop of Kilmacduagh since 1744, became Apostolic Administrator of Kilfenora in September 1750.

Following the resignation of Bishop Patrick Fallon in 1866, John McEvilly, Bishop of Galway (later Archbishop of Tuam), was appointed Apostolic Administrator of both the dioceses of Kilmacduagh and Kilfenora. In 1883, the see of Kilmacduagh was united with Galway, and the bishops of the united see were also made permanently apostolic administrators of Kilfenora.
