Eochu (or Eochaid) Apthach ("outlaw" or "fatal")[1] of the Corcu Loígde of County Cork, a distant descendant of Breogán, the father of Míl Espáine, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
He took power after killing the previous incumbent, Bres Rí.
He was killed by Finn mac Blatha, a descendant of Ollom Fotla.
The Lebor Gabála Érenn synchronises his reign with that of Darius the Great of Persia (522–485 BC).
