Archbishop of Cardiff-Menevia

The Archbishop of Cardiff-Menevia is the ordinary of the Roman Catholic Archdiocese of Cardiff-Menevia.

The position came about after the merger of the Archdiocese of Cardiff and the Diocese of Menevia in 2024, after the positions of bishops of those dioceses were held by the same person, Mark O'Toole. The archdiocese covers an area of 10,899 square miles (28,230 km²) and spans the historic county of Herefordshire and all of South Wales. The metropolitan see of the previous archdiocese was in the city of Cardiff where the archbishop's seat was located at the Metropolitan Cathedral Church of St David and the seat of the Diocese of Menevia was in St Joseph's Cathedral, Swansea.

With the exception of the second archbishop, Francis Mostyn, born in Flintshire and of local descent, the Welsh connections of the archbishops and bishops have been extremely weak. Ireland, London and the English provinces have supplied a majority.

The see is currently held by Mark O'Toole, the 1st Archbishop of Cardiff-Menevia. He was originally the 8th and last Archbishop of Cardiff and 12th and last Bishop of Menevia, who was appointed by the Holy See on 27 April 2022 and installed at St David's Cathedral, Cardiff on 20 June and St Joseph's Cathedral, Swansea on 23 June 2022.
