Óengus Olmucaid (or Aengus Olmucada), son of Fíachu Labrainne, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
He fought many battles against the Cruithne, the Fir Bolg, the Fomorians and other peoples of Ireland, the people of the Orkney islands, and even the Longobardi.
He was killed by Enna Airgdech, son of Eochu Mumu, in the battle of Carman, continuing the feud between the descendants of Erimon and Éber Finn.
Geoffrey Keating, who interprets his epithet as meaning "great hogs", dates his reign to 1050–1032 BC, the Annals of the Four Masters to 1428–1410 BC.
