Mathgamain was the son ofCennétig mac Lorcáinof theDál gCais.^[1]His father died in 951 and is called king ofTuadmumuin the report of his death, and was probably succeeded by Mathgamain's brother Lachtna, who was assassinated in 953 by rival septs of the Dál gCais (The Uí Fhloinn and Uí Chearnaigh). After this Mathgamain succeeded him.

In 967, Mathgamain is called "king of Cashel", by theAnnals of Ulster.^[2]However he is not believed to have become king of Munster until 970 or shortly after, deposingMáel Muad mac Brain.In 967, Mathgamain defeatedIvar of Limerickin the celebratedBattle of Sulcoit,following raids by Mathgamain into Ui Fidgente territory in 964. The most common account of Mathgamain's death was that he was captured in 976 byDonnubán mac Cathail,Tigerna(Chief of the Name) of theIrish clan Uí Fidgenti,with whom the Dál gCais were vying for territory, and who were in alliance withHiberno-NorseKingIvar of Limerick.Donnubán handed him over to his most powerful allyMáel Muad mac Brain(Mulloy, son of Brain) previous king of Munster, who had Mathgamain killed.^[3]
