In Greek mythology, Sarpedon referred to at least three different people.

Sarpedon (son of Zeus and Laodamia)
A third Sarpedon was a Thracian son of Poseidon, and brother to Poltys, King of Aenus. Unlike the other two Sarpedons, this Thracian Sarpedon was not a hero, but an insolent individual who was killed by Heracles.
