Nydri (Greek: Νυδρί) is a town and a community on the eastern coast of the island of Lefkada, Greece.

The Greek National Road 42 (Vasiliki - Lefkada (city) - Amfilochia) passes through the town.

In the sea in front of Nydri are several small islands including Madouri, Skorpios, Skorpidi and Sparti.

The German archaeologist Wilhelm Dörpfeld, having examined the geographical descriptions of Homer in the Iliad and the Odyssey believed that Lefkada was Homer's 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.
