In Greek mythology, Antiphus or Antiphos (Ancient Greek Ἄντιφος) is a name attributed to many men. The atlas node antiphus-thessalus-cos is the Coan captain — son of Thessalus son of Heracles and brother of Pheidippus — who with his brother leads the island contingent (Cos, Calydnae, Carpathus, Casus, Nisyrus) to Troy with thirty ships, and in later tradition gives Thessaly its name from their father.

I.Coan captain at Troy
Homer's Catalogue of Ships pairs Antiphus and Pheidippus as sons of Thessalus leading the Coans and their island dependencies. Apollodorus and Hyginus preserve the same double command; a later belief makes Antiphus the invader who names a region of Greece Thessaly after his father.
Homonym guard: not Antiphus son of Priam; not the Maeonian ally Antiphus son of Talaemenes (antiphus-maeonian); not Odysseus' companion eaten by Polyphemus; not the Phthian son of Myrmidon. The atlas id is the Coan Heraclid captain alone.
