This is a list of the kings of Dál Riata, a kingdom of Irish origin which was located in Scotland and Ireland.
Most kings of Dál Riata, along with later rulers of Alba and of Scotland, traced their descent from Fergus Mór mac Eirc, and even in the 16th century, James VI of Scotland called himself the "happie monarch sprung of Ferguse race".
After the disastrous Battle of Moira (Mag Rath) in 637, Irish Dál Riata lost possession of its Scottish lands.
The last attested king of Scottish Dál Riata is Fergus mac Echdach, brother of and successor to Áed Find, whose death is reported in the Annals of Ulster in 781.
Dál Riata was divided into a number of kingroups or dynasties, called cenéla, among which was the Cenél nGabráin of Kintyre, who claimed descent from Gabrán mac Domangairt, and the Cenél Loairn, who claimed descent from Loarn mac Eirc.
