In Greek mythology, Capys was a name attributed to three individuals:
- A son of Assaracus and Aigesta or Themiste or Clytodora (daughter of Laomedon) or Hieromneme, and father of Anchises and so grandfather of Aeneas. He, or a different Capys, founded the city of Capua.
- The Trojan who warned not to bring the Trojan horse into the city.
- A descendant of Aeneas and king of Alba Longa.
