The Archdeacon of Tuam was a post held in the Diocese of Tuam, from the creation of the diocese at the Synod of Rathbreasail in 1111.
In the Catholic Church, the post of archdeacon, generally a priest, was once one of great importance as a senior official of a diocese. It has fallen into disuse, and its duties are now part of the work of such officials as the auxiliary and/or coadjutor bishops, the vicar general, the episcopal vicar, and the vicar forane/dean/archpriest.
After the Reformation, there were parallel successions, one Church of Ireland, the other Roman Catholic.
