Ionian Sea ( Greek: ?, Iónio Pélagos ; [i'onio 'pela?os] Italian: Mar Ionio ; [mar 'j?:njo] Albanian: Deti Jon ) is an elongated [d?ti j?:n] bay of the Mediterranean Sea, south of the Adriatic Sea. It is bounded by Southern Italy including Calabria, Sicily, and the Salento peninsula to the west, southern Albania to the north, and the west coast of Greece.
All major islands in the sea belong to
Greece. They are collectively named the Ionian Islands, the main ones being Corfu, Kefalonia, Zakynthos, Lefkada, and Ithaca.
There are ferry routes between Patras and Igoumenitsa, Greece, and Brindisi and Ancona, Italy, that cross the east and north of the Ionian Sea, and from Piraeus westward. Calypso Deep, the deepest point in the Mediterranean at -5,267 m (-17,280 ft), is located in the Ionian Sea, at . 36°34?N 21°8?E / 36.567°N 21.133°E  The sea is one of the most  seismically active areas in the world.

Ionian comes from the Greek language (?). Its etymology is unknown. Ancient Greek writers, especially  Aeschylus, linked it to the myth of Io. In Ancient Greek the adjective Ionios ( ) was used as an epithet for the sea because Io swam across it.   According to the  , the name may derive from Oxford Classical Dictionary Ionians who sailed to the West. There were also narratives about other  eponymic legendary figures; according to one version,  Ionius was a son of Adrias (eponymic for the Adriatic Sea); according to another, Ionius was a son of . Dyrrhachus When Dyrrhachus was attacked by his own brothers,  Heracles, who was passing through the area, came to his aid, but in the fight the hero killed his ally's son by mistake. The body was cast into the water, and thereafter was called the Ionian Sea. 
International Hydrographic Organization defines the limits of the Ionian Sea as follows:  On the North. A line running from the mouth of the Butrinto River (39°44'N) in Albania, to Cape Karagol in Corfu (39°45'N), along the North Coast of Corfu to Cape Kephali (39°45'N) and from thence to Cape Santa Maria di Leuca in Italy. On the East. From the mouth of the Butrinto River in Albania down the coast of the mainland to Cape Matapan. On the South. A line from Cape Matapan to Cape Passero, the Southern point of Sicily. On the West. The East coast of Sicily and the Southeast coast of Italy to Cape Santa Maria di Leuca.
