The Abbot of Dundrennan was the head of the Cistercian monastic community of Dundrennan Abbey, Galloway. It was founded by Fergus of Galloway in 1142. Dundrennan was a large and powerful monastery in the context of the south-west. It became secularised and protestantised in the 16th century. In 1606 it was finally turned into a secular lordship in for John Murray of Lochmaben, afterwards earl of Annandale.
The royal warrant in 1886 which revived the office of Dean of the Chapel Royal also gave the Dean the titles of Abbot of Crossraguel and Abbot of Dundrennan.[1]
