The Diocese of Clogher (Latin: Dioecesis Clogheriensis; Irish: Deoise Chlochair) is a Latin Church diocese of the Catholic Church in Ireland. It was formed in 1111 at the Synod of Rathbreasail as the see for the Kingdom of Uí Chremthainn. It is part of the Province of Armagh.

The original cathedral was in the village of Clogher in County Tyrone, site of a monastery founded in 454 by St. Macartan, who was appointed bishop by St. Patrick in the 5th century. Following the Reformation, Henry VIII confiscated Clogher Cathedral for his Church of Ireland and the Roman Catholic diocese was without a permanent see until 1851 when a decision was made to move to the larger town of Monaghan, 32 kilometres south east of Clogher village. The foundation stone of a St Macartan's Cathedral was laid in Monaghan in June 1861.^[1] The cathedral was dedicated in August 1892.

Today the diocese has a faithful of over 100,000 parishioners spread across 37 parishes. The current bishop is the Most Reverend Lawrence Duffy, who was appointed by the Holy See on 8 December 2018 and ordained bishop on 10 February 2019.^[2][3]
