Zakynthos or Zante is a Greek island in the Ionian Sea. It is the third largest of the Ionian Islands, with an area of 405.55 km2 (156.6 sq mi), and a coastline 123 km (76 mi) in length. 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 Zacynthus, the son of the legendary Arcadian chief Dardanus.

The Ionian Sea is an elongated bay of the Mediterranean Sea. It is connected to the Adriatic Sea to the north, and is bounded by Southern Italy, including Basilicata, Calabria, Sicily, and the Salento peninsula to the west, southern Albania to the north, and the west coast of Greece, including the Peloponnese.
