In Greek mythology, Zakynthos (Greek: Ζάκυνθος) (alternatively Zacynthus) was the son of the legendary Arcadian chief Dardanus. The name, like all similar names ending in -nthos, is pre-Mycenaean or Pelasgian in origin.
Dardanus' children by Batea were Ilus, Erichthonius and Idaea. According to Dionysius of Halicarnassus (1.50.3), Dardanus also had a son named Zacynthus by Bataea and this Zacynthus was the first settler on the island afterwards called Zakynthos.
Zakynthos is depicted on the flag of Zakynthos.
