The Lords of Kinelarty were Gaelic gentry located in County Down, in Ireland, lasting until the Tudor conquest of Ireland. There does not appear to be any single list of the chieftains who held demesne over the region, as they are mentioned randomly in the ancient Irish annals. It is traditionally the tribal territory of the clan Macartan who dominated local political until the end of the 16th century.
Kinelarty derives its name from the Irish Cineál Fhaghartaigh, meaning Faghartach's (Fogarty's) kindred, which related to Foghatach macCartan, who reigned as one of the sovereigns over the area.
