Zakynthos is a Greek island in the Ionian Sea. It is the third largest of the Ionian Islands.

The name, like all similar names ending in -nthos, is pre-Mycenaean or Pelasgian in origin. In Greek mythology the island was said to be named after Zakynthos, the son of a legendary Arcadian chief Dardanus.

Zakynthos is a tourist destination, with an international airport served by charter flights from northern Europe. The island's nickname is To fioro tou Levante (Italian: Il fiore di Levante, English: The flower of the East), given by the Venetians.
