The Bishop of Cork was a separate episcopal title which took its name after the city of Cork in Ireland. The title is now united with other bishoprics. In the Church of Ireland it is held by the Bishop of Cork, Cloyne and Ross, and in the Roman Catholic Church it is held by the Bishop of Cork and Ross.
On 30 July 1326, Pope John XXII, on the petition of King Edward II of England, issued a papal bull for the union of the bishoprics of Cork and Cloyne, the union to take effect on the death of either bishop. The union should have taken effect on the death of Philip of Slane in 1327, however, bishops were still appointed to each separate bishopric. The union eventually took place with Jordan Purcell appointed bishop of the united see of Cork and Cloyne in 1429.

The see of Cork remained a separate bishopric until 19 April 1958 when it united with Ross to form the current united bishopric of Cork and Ross.
