Pheidippus or Phidippus (Ancient Greek: Φείδιππος, "he who spares the horses") is a son of Thessalus and Chalciope, brother of Antiphus, and a Heraclid captain of Cos in the Trojan War. With Antiphus he leads thirty ships from the Dodecanese islands; after the war tradition sends him to Andros and Cyprus.

I.Coan captain at Troy
Homer's Catalogue of Ships counts Pheidippus and Antiphus, the two sons of king Thessalus son of Heracles, among the island chiefs who held Nisyrus, Crapathus, Casus, Cos (the city of Eurypylus), and the Calydnian isles, with thirty hollow ships. Apollodorus' Trojan catalogue likewise sets them over the Coans with thirty ships.
Hyginus includes Phidippus among the suitors of Helen, so his presence at Troy follows the oath of the suitors as well as the Heraclid island command.
II.After the war
When the Greek fleet was scattered by storm, Apollodorus says Phidippus and the Coans settled at Andros, while Antiphus went to the land of the Pelasgians and named it Thessaly after their father. Other notices have the brothers invade that land together, or connect a third brother Nesson with the regional name Nessonis.
A further Apollodoran strand drives Phidippus from Andros on to Cyprus, where he settled — a nostos beyond his Coan homeland.
