Nuadu Necht ("the pure"),[1] son of Sétna Sithbac, a descendant of Crimthann Coscrach, of the Laigin, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
The Lebor Gabála Érenn synchronises his reign with that of the Roman emperor Augustus (27 BC – AD 14), and after the birth of Christ, and makes him contemporary with legendary provincial kings Conchobar mac Nessa, Cairbre Nia Fer and Ailill mac Máta.
[4] The Four Masters combine his reign with that of Ér, Orba, Ferón and Fergna centuries before, to make a whole year in their chronology.
Sometimes the father of the druid Tadg mac Nuadat, whose daughter, Muirne, is Fionn's mother is mistaken as Nuadu Nect, when it is in fact Nuada Airgetlám of the Tuatha Dé Danann.
