Ailill Inbanda mac Eógain (died 549) was a king of Connacht from the Ui Fiachrach branch of the Connachta. He was the son and successor of Eógan Bél, who was slain by the northern Ui Neill in 542. His nickname Inbanda means "womanish" or effeminate or it could mean "the vigorous" which is more likely (see eDill).
