The Bishop of Clonfert (Irish: Easpag Chluain Fearta) is an episcopal title which takes its name after the village of Clonfert in County Galway, Ireland.
During the Reformation, the bishops changed their allegiance back and forth between the Pope and the Crown.
In the Roman Catholic Church, the title remains a separate bishopric.
The current incumbent is the Most Reverend Michael Duignan, Bishop of the Roman Catholic Diocese of Clonfert, who was appointed on 16 July 2019 and ordained bishop on 13 October 2019.
In 2021 the Holy See determined that the diocese of Clonfert and the Roman Catholic Diocese of Galway, Kilmacduagh and Kilfenora would share a bishop.
