The lesser-known of two Conáns in the Fenian Cycle. The son of Liath Luachra, from whom Fionn gained the crane bag. Conán was a marauder opposing the Fenians for many years, but when he was overcome one day in Munster, he changed his allegiances and joined Fionn and his men, becoming a keen and hardy fighter. In some stories he mistreats Finnine, the sister of Ferdoman, sometimes while described as her husband. To avenge his sister's honour, Ferdoman engages Conán in a duel in which they both die.
