In Greek mythology, Leucippus, son of Gorgophone and Perieres, was the father of Phoebe and Hilaeira, and also of Arsinoe mother (in some versions of the myth) of Asclepius, by his wife Philodice, daughter of Inachus. Castor and Polydeuces abducted and married Phoebe and Hilaeira, the daughters of Leucippus. In return, Idas and Lynceus, nephews of Leucippus (or rival suitors), killed Castor. Polydeuces was granted immortality by Zeus, and further persuaded Zeus to share his gift with Castor. Ovid VIII, 306. Other people in Greek mythology with the name Leucippus include:
- The son of Heracles and Eurytele, daughter of Thespius
- The Calydonian hunter son of Hippocoon
- The daughter of Lamprus and Galatea, who was turned by Leto into a son
- The son of Oenomaus and companion of Daphne
- The son of Poemander who was killed accidentally by his father
- Leucippus, the son of Thurimachus and king of Sicyon
