Báetán moccu Chormaic, abbot of Clonmacnoise, died 1 March 664.
Báetán was a member of the Moccu Chormaic, a prominent line of the Conmaicne Mara (now Connemara).
In 653 he became ninth abbot of Clonmacnoise in succession to Aedlug mac Caman.
He held office for twelve years, a considerable period considering most candidates were elderly.
He was succeeded by Colmán Cass mac Fualascaig, of the Corcu Moga of what is now north-east County Galway
