Castledermot Abbey (Irish: Mainistir Dhíseart Diarmada)[2] is a ruined Franciscan friary in Castledermot, County Kildare, Ireland. It was founded at some point before 1247. A previous monastery had been founded on the same site by Diarmait, a son of Áed Róin, King of Ulster, in the ninth century AD.
