Dúnchad mac Cinn Fáelad was the eleventh abbot of Iona (707–717). He was the son of Cenn Fáelad, and grandson of Máel Coba, of the Cenél Conaill. While most early abbots of Iona were members of Cenél Conaill they came from minor branches of the kindred, but Dúnchad came from the ruling line, grandson of one High King of Ireland and the nephew of two others, Cellach and Conall.
