The **Bishop of Clonfert** ([Irish](/source/Irish_language): *Easpag Chluain Fearta*) is an [episcopal](/source/Episcopal_polity) title which takes its name after the village of [Clonfert](/source/Clonfert) in [County Galway](/source/County_Galway), [Ireland](/source/Republic_of_Ireland). In the [Roman Catholic Church](/source/Roman_Catholic_Church) it remains as a separate title; but in the [Church of Ireland](/source/Church_of_Ireland) it has been united with other bishoprics.

## History

The [diocese](/source/Diocese) of Clonfert was one of the twenty-four dioceses established at the [Synod of Rathbreasail](/source/Synod_of_Rathbreasail) in 1111, and its boundaries were fixed at the [Synod of Kells](/source/Synod_of_Kells) in 1152. During the [Reformation](/source/Reformation_in_Ireland), the bishops changed their allegiance back and forth between the Pope and the [Crown](/source/The_Crown). After the Reformation, there were parallel [apostolic successions](/source/Apostolic_succession).

In the [Church of Ireland](/source/Church_of_Ireland), the title continued until 1625, when it united with [Kilmacduagh](/source/Bishop_of_Kilmacduagh), forming the united see of [Clonfert and Kilmacduagh](/source/Bishop_of_Clonfert_and_Kilmacduagh).

In the [Roman Catholic Church](/source/Roman_Catholic_Church), the title remains a separate bishopric. The current incumbent is the Most Reverend [Michael Duignan](/source/Michael_Duignan_(bishop)), Bishop of the [Roman Catholic Diocese of Clonfert](/source/Roman_Catholic_Diocese_of_Clonfert), who was [appointed](/source/Appointment_of_Catholic_bishops) on 16 July 2019 and [ordained bishop](/source/Bishop_(Catholicism)) on 13 October 2019. In 2021 the [Holy See](/source/Holy_See) determined that the diocese of Clonfert and the [Roman Catholic Diocese of Galway, Kilmacduagh and Kilfenora](/source/Roman_Catholic_Diocese_of_Galway%2C_Kilmacduagh_and_Kilfenora) would share a bishop.[1]
