In Greek mythology, Philonoe (Ancient Greek Φιλονόη; also Phylonoe) is daughter of Iobates of Lycia and wife of Bellerophon. After the hero survives the Chimera, the Amazons, and further trials, the king gives him Philonoe and half the kingdom; she bears Isander (Peisander), Hippolochus, and Laodameia, mother of Sarpedon. She is sister of Stheneboea and must not be confused with the Spartan Phylonoe whom Artemis made immortal.

I.Family and marriage
Philonoe is daughter of Iobates (or of the Lycian king who receives Bellerophon) and sister of Stheneboea, wife of Proetus of Argos. Homer says that when the king saw Bellerophon was the valiant offspring of a god, he kept him, gave him his daughter, and shared half his kingly honour; dying, he bequeathed the realm to the hero.
Apollodorus names the bride Philonoe. By Bellerophon she becomes mother of Isander, Hippolochus, and Laodameia (also called Deidamia or Hippodamia). With Laodameia Zeus begets Sarpedon, linking the Corinthian hero's Lycian line to the captains who fight beside Hector.
II.Mythology
Her marriage is the reward that closes Bellerophon's Lycian labours after the false accusation and death-token sent by Stheneboea. Hyginus adds that Stheneboea, hearing of the wedding, killed herself out of love and shame.
Philonoe herself has little separate narrative; her importance is as queen of the Lycian house from which Glaucus and Sarpedon descend.
III.Homonyms
This atlas entry (philonoe-lycia) is Iobates' daughter and Bellerophon's wife. She is distinct from Phylonoe (phylonoe), the Spartan princess daughter of Tyndareus and Leda whom Artemis made immortal — sister of Helen and Clytemnestra, with no part in the Lycian trials.
