Carystus or Carystos (; Ancient Greek: Κάρυστος) or Carycus, in Greek mythology, was the son of Chiron and a nymph Chariclo, brother of Hippe, Endeïs and Ocyrhoe. Carystus was the father of Zarex,[1] and also, a certain Aristaeus. In another version of the myth, his son Petraeus was the father of Zarax instead.[2] The town of Carystus on Euboea took the name from him.[3]
