Énna Aignech ("spirited, swift", an epithet usually applied to horses),[1] son of Óengus Tuirmech Temrach, was, according to medieval Irish legend, a High King of Ireland.
He took power after killing his predecessor, and relative's killer, Nia Segamain, and ruled for twenty or twenty-eight years, after which he was killed by Crimthann Coscrach, the grandson of the man who had killed Énna's grandfather, in the Battle of Ard Crimthainn.
Crimthann was killed by Rudraige mac Sithrigi, the great-grandson of the killer of one of Énna's ancestors.
The Lebor Gabála Érenn synchronises his reign with that of Ptolemy VIII Physcon in Egypt (145–116 BC).
