Ferghus Scannal mac Crimthainn ("Fergus of the Disputes, son of Crimthann"; died AD 582)[1] (although the Annals of the Four Masters note the death occurred in the year 580) [2] was a king of Munster from the Eóganacht Airthir Cliach branch of the Eoganachta, the ruling dynasty of Munster.
He is mentioned in king lists such as the Laud Synchronisms and the Book of Leinster.
According to the Annals of Tigernach, he succeeded Coirpre Cromm mac Crimthainn as king in 577 but was slain shortly thereafter in 582.
According to Eogannacht sources, he was slain by the Leinstermen who forfeited Osraige to Munster as a blood-fine for this deed.
