Finnat Már ("the great", later spellings Innatmar, Ionnadmhar) son of Nia Segamain, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
He succeeded to the throne after the death of Rudraige mac Sithrigi of plague, but after a reign of one, three or nine years he was killed by Rudraige's son Bresal Bó-Díbad.
The Lebor Gabála Érenn synchronises his reign with that of Ptolemy X Alexander I (110–88 BC) in Egypt.
[1] The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 154–151 BC,[2] that of the Annals of the Four Masters to 219–210 BC.
