The Gulf of Corinth or the Corinthian Gulf 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 at Cape Drepano, where the narrowest point is crossed by the Rion-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 seismic regions in Europe.
