The Dean of Cashel is the head of the Chapter of the Cathedral Church of St John the Baptist and St Patrick's Rock, Cashel, one of the Church of Ireland cathedrals of the united Diocese of Cashel, Ferns and Ossory. The Deanery is vacant. Following the Reformation, the Church of Ireland retained the cathedral until it was closed for worship in 1721. Meanwhile, the old parish Church of St John in Cashel was removed and the present Georgian Cathedral completed in 1784. The most recent dean, the Very Reverend Gerald G. Field, was instituted and installed in February 2014.
