Dui Finn, son of Sétna Innarraid, is a figure from medieval Irish legend who was said to be High King of Ireland. He seized the throne by killing Siomón Brecc, the man who had killed his father. Dui Finn reigned for ten years before Siomón’s son Muiredach Bolgrach killed him. The Lebor Gabála Érenn links his reign to the Persian kings Xerxes I (485–465 BC) and Artaxerxes I (465–424 BC). Different Irish sources give different dates for his reign: Geoffrey Keating’s Foras Feasa ar Éirinn places it at 679–674 BC, while the Annals of the Four Masters give 904–894 BC.
