Muiredach Bolgrach, son of Siomón Brecc, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
He took power after killing his predecessor, and his father's killer, Dui Finn, ruled for 13 months or four years depending on the source consulted, and was then killed by Dui's son Énna Derg.
The Lebor Gabála Érenn synchronises his reign with that of Artaxerxes I of Persia (465–424 BC).
