In Greek mythology, Clytoneus (Ancient Greek Κλυτόνηος) is a Phaeacian prince — son of King Alcinous and Arete, brother of Nausicaa, Halius, and Laodamas. In the Odyssey games for Odysseus he far outstrips every Phaeacian in the foot-race.

I.Godlike runner of Scheria
Homer (Odyssey 8.119–125) has Clytoneus win the foot-race among the Phaeacians entertaining Odysseus, shooting to the front by as much as a fallow-team of mules outpaces the rest. Wikipedia lists him as prince of Corcyra (the later identification of Scheria) and brother of Nausicaa, Halius, and Laodamas.
The same Wikipedia page also covers Clytoneus/Clytius son of Naubolus of Argos, father of the Argonaut Nauplius — a different figure.
II.Homonym care
The atlas id clytoneus-phaeacian is Alcinous' son alone — not the Argive Naubolid.
