The Corinth Canal is an artificial canal in Greece that connects the Gulf of Corinth in the Ionian Sea with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnese from the Greek mainland, making the peninsula an island. The canal was dug through the Isthmus at sea level and has no locks. It is 6.4 kilometres in length and only 24.6 metres wide at sea level, making it impassable for many modern ships. It is currently of little economic importance and is mainly a tourist attraction.

Corinth is the successor to an ancient city, and is a former municipality in Corinthia, Peloponnese, which is located in south-central Greece. Since the 2011 local government reform, it has been part of the municipality of Corinth, of which it is the seat and a municipal unit. It is the capital of Corinthia.
