Corinthia (Greek: Κορινθία, Korinthía) is a peripheral unit of Greece, part of the periphery of Peloponnese. It is the third-most populated peripheral unit on the Peloponnese peninsula and the largest in the region since the 1980s when it surpassed the neighboring Arcadia's population in which it is now placed below. Currently (2001 census) the population stands at 144,527 persons, while the 1991 figures showed a population of 132,139 persons.
The Corinth Canal, carrying ship traffic between the northern Mediterranean and the Aegean, is about 4 km east of Corinth, cutting through the Isthmus of Corinth. Agioi Theodoroi is the easternmost Corinthian community and is considered a suburb of Athens.
The area around Corinth and the western Saronic including the southeastern part are made up of fault lines including the Corinth Fault and the Poseidon Fault and includes one running from Perahcora to Agioi Theodoroi. More faults are near Kiras Vrysi and Sofiko.
