The Diocese of Menevia (Latin: Dioecesis Menevensis) was a Latin Church diocese of the Catholic Church in Wales. It was one of two suffragan dioceses in the ecclesiastical province of Cardiff and was subject to the Archdiocese of Cardiff, until it merged with the archdiocese in 2024, to form the Roman Catholic Archdiocese of Cardiff-Menevia.
