Lefkada (Greek: Λευκάδα, Lefkáda, [lefˈkaða]), also known as Lefkas or Leukas (Ancient Greek and Katharevousa: Λευκάς, Leukás, modern pronunciation Lefkás) and Leucadia, is a Greek island in the Ionian Sea on the west coast of Greece, connected to the mainland by a long causeway and floating bridge. The principal town of the island and seat of the municipality is Lefkada

Nydri (Greek: Νυδρί) is a town and a community on the eastern coast of the island of Lefkada, Greece. It is part of the municipal unit Ellomenos. The community includes the small village Rachi. The Greek National Road 42 (Vasiliki - Lefkada (city) - Amfilochia) passes through the town. Nydri is a popular tourist town. In the sea in front of Nydri are several small islands including Madouri, Skorpios, Skorpidi and Sparti. The island Skorpios is the property of the Ribolovlev family.

The German archaeologist Wilhelm Dörpfeld, having examined the geographical descriptions of Homer in the Iliad and the Odyssey believed that Lefkada was Homerʼs Ithaca, and that the palace of Odysseus was located west of Nydri on the south coast of Lefkada. He performed extensive excavations at Nydri and uncovered Mycenaean tombs, walls, ruins and artefacts which supported his hypothesis. Dörpfeld spent the last years of his life at Nydri and he is buried there.
