The Abbot of Iona was the head of Iona Abbey during the Middle Ages and the leader of the monastic community of Iona, as well as the overlord of scores of monasteries in both Scotland and Ireland, including Durrow, Kells and, until the Synod of Whitby, Lindisfarne. It was one of the most prestigious clerical positions in Dark Age Europe, and was visited by kings and bishops of the Picts, Franks and English. The Ionan abbots also had the status of Comarba of Colum Cille, i.e. the successors of that Saint, Columba.
