Corfu is a Greek island in the Ionian Sea. It is the second largest of the Ionian Islands. Its northern part lies off the coast of Sarandë, Albania, from which it is separated by straits varying in breadth from 3 to 23 km (2 to 15 mi), including one near ancient Butrint, while its southern part lies off the coast of Thesprotia, Greece.
The island is part of the Corfu Prefecture and includes twelve of the sixteen municipalities or communes in the prefecture and communities of Ereikoussa, Mathraki, Othonoi, and Municipality of Paxoi, which are all separate islands.
The principal town (pop. 28,185) of the island is also named Corfu, or Kérkyra in Greek, as is its municipality (pop. 39,487). Corfu is home to the Ionian University. The island is connected to the history of Greece from the beginning of Greek mythology.
