Eochaid mac Echdach was king of Dál Riata (modern western Scotland) from 726 until 733. Dál Riata (also Dalriada or Dalriata) was a Gaelic overkingdom on the western seaboard of Scotland with some territory on the northern Scotland ( Gaelic: Alba) is a Country in northwest Europethat occupies the northern third of the island of Great Britain.

Eochaid came to power as king of Dál Riata in 726, presumably deposing Dúngal mac Selbaig. Dúngal mac Selbaig was king of Dál Riata. His reign can best be placed in the years 723 to 726 beginning with the abdication of his father Selbach mac Ferchair Selbach may have tried to restore his son to power, and fought against Eochaid's supporters at Irros Foichnae in 727, but without apparent success. Selbach mac Ferchair was king of the Cenél Loairn and of Dál Riata. The annals vary as to whether the despatch of a fleet from Dál Riata to Ireland to aid Flaithbertach mac Loingsig in his war with Áed Allán should be placed in the reign of Eochaid, or that of his successor. Ireland (pronounced /ˈaɾlənd/ Éire) is the third largest island in Europe, and the twentieth-largest island in the world Flaithbertach mac Loingsig (died 765 was a High King of Ireland. Áed Allán (or Áed mac Fergaile) (died 743 was an 8th century Irish King of Ailech and High King of Ireland.
At his death in 733, Eochaid is named king rather than lord of Dál Riata, which may suggest that after the defeat of Dúngal and Selbach his reign was unchallenged. His son, Áed Find, was later king of Dál Riata. Áed Find (Áed the White or Áed mac Echdach (before 736&ndash778 was king of Dál Riata (modern western Scotland)
As Dál Riata certainly maintained a separate existence until 736, Eochaid must have had a successor, or successors. It appears that he was succeeded by Muiredach mac Ainbcellaig, who had replaced Dúngal mac Selbaig as king of the Cenél Loairn. Muiredach mac Ainbcellaig was king of the Cenél Loairn, and of Dál Riata (modern western Scotland) from about 733 until 736 Loarn mac Eirc was a legendary king of Dál Riata who may have lived in the 5th century
