The Carmarthen Deanery is a Roman Catholic deanery in the Diocese of Menevia that covers several churches in Carmarthenshire and the surrounding area.[1] In the early 2010s, the Aberystwyth Deanery was dissolved and the church in Lampeter became part of the Carmarthen Deanery.
The deanery is centred at Blessed Sacrament Church in Gorseinon.[2]
