The Gulf of Corinth or the Corinthian Gulf (Κορινθιακός Kόλπος, Korinthiakόs Kόlpos, in Greek) is a deep inlet of the Ionian Sea separating the Peloponnese from western mainland Greece. It is bounded in the east by the Isthmus of Corinth which includes the shipping route of the Corinth Canal, and in the west by the Strait of Rion, which separates the Gulf of Corinth from the outer Gulf of Patras where the narrowest point is crossed by the Rio-Antirio bridge. The Gulf of Corinth is almost surrounded by the prefectures of Aetolia-Acarnania, Phocis in the north, Boeotia in the northeast, Attica in the east, Corinthia in the southeast and south and Achaea in the southwest. The gulf is one of the most seismically active regions in Europe.

In medieval times, the gulf was known as the Gulf of Lepanto (the Italian form of Naupactus).

The shipping routes between Athens and to the ports of the rest of the world including the Mediterranean ports pass along this gulf. Ferry routes link Aigio and Agios Nikolaos in the western part of the gulf.

  • Length: 130 km (81 mi)
  • Width: 8.4 to 32 km (5.2 to 19.9 mi)
  • Max Depth 935 m (3,068 ft)


The Gulf was created by the expansion of a tectonic rift due to the westward movement of the Anatolian Plate, and expands by 10 mm (0.39 in) per year.[1] The surrounding faults can produce earthquakes up to magnitude 6.8, though they are relatively uncommon.


Cetaceans such as Fin Whales or dolphins are known to come into the Corinthian gulf occasionally.[2]
