In Greek mythology, Teleon (Ancient Greek: Τελέων, gen. Τελέοντος, lit. 'the completer', 'fulfiller' or 'one who reaches an aim') may refer to the following two distinct characters:
Teleon, also called Geleon (Γελέων), the Athenian son of Ion, eponym of the Ionians, and brother of Aegicoreus, Argades and Hoples. The earlier four tribes of Athens: Teleontes (Teleonites)/ Geleontes, Aegicoreis, Argadeis (Ergadeis) and Hopletes (Hoplites) were named after him and his siblings. Later on, Teleon fathered Butes, one of the Argonauts, by his naiad-wife Zeuxippe, daughter of the river god Eridanos.
Teleon, the Locrian father of Eribotes, another Argonaut. Apollonius describes Teleon as "virtuous" (ἀγαθός), but beyond that, no information on this figure is available.
