Othonoi (Greek: Οθωνοί, Italian: Fanò) is an island and a former community of the Ionian Islands, Greece. Since the 2011 local government reform it is part of the municipality of Corfu, of which it is a municipal unit. It is the westernmost point of Greece, located northwest of Corfu. Population 631 (2001). In the 19th century the island used to be the capital of the Diapontia Islands municipality, which also included nearby islands of Ereikoussa and Mathraki. Most of the island's inhabitants can trace their origins to Paxi island, south of Corfu, as people from Paxi were settled in the island beginning in the 1570s by the Venetian Republic. A cave, near the Aspri Ammos (White Sand) beach, is traditionally believed to have been the place where Calypso kept Odysseus captive.
