Adamair (
Adammair,
Adhamair,
Amadir), son of
Fer Corb, was, according to medieval Irish legends and historical traditions, a
High King of Ireland. He came from
Munster, killed the previous incumbent,
Ailill Caisfhiaclach, and reigned for five years, until he was killed by
Eochaid Ailtleathan. The
Lebor Gabála Érenn synchronises his reign with that of
Ptolemy V Epiphanes in
Egypt (204–181 BC). The chronology of the
Annals of the Four Masters dates his reign to 418–414 BC, the chronology of
Geoffrey Keating's
Foras Feasa ar Éirinn to 290–285 BC. He was the husband of the presumed goddess
Flidais of the
Tuatha Dé Danann.
