Báetán mac Ninneda (died 586) was an Irish king of the Cenél Conaill, a sept of the northern Uí Néill.
He was the son of Ninnid mac Duach (flourished 561–563) and great grandson of Conall Gulban (died 464).
[2] It is difficult to disentangle the reign of Báetán from that of his younger second cousin Áed mac Ainmuirech (died 598).
Whether Báetán was king of Tara or not, the real effective power among the northern Uí Néill from 572 was Áed mac Ainmuirech.
[6] His death is recorded in the annals in 586 when he was killed at Léim in Eich (Lemanroy, Termoneeny parish, County Londonderry) at the instigation of Colmán Bec (died 587), the southern Uí Néill King of Uisnech who was making a bid for the high kingship.
