Sírlám, son of Finn mac Blatha, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
He took power after killing his predecessor, Lugaid Íardonn, in Ráth Clochair.
He ruled for thirteen years according to the Lebor Gabála Érenn,[2] or sixteen according to Geoffrey Keating[3] and the Four Masters.
The Lebor Gabála synchronises his reign with that of Artaxerxes I of Persia (465–424 BC).
