Antirrio (Greek: Αντίρριο, pronounced [aˈndirio], Latin: Antirrhium) is a town and a former municipality in Aetolia-Acarnania, West Greece, Greece. Since the 2011 local government reform it is part of the municipality Nafpaktia, of which it is a municipal unit. The municipal unit has an area of 50.794 km.

It is situated on the north side of the narrow (2.4 km) Strait of Rio, which separates the Gulf of Patras in the west from the Gulf of Corinth in the east. Since August 2004 the Rio–Antirrio bridge connects northwestern Greece with the Peloponnese. The name Antirrio means "opposite Rio".

Nafpaktos (Greek: Ναύπακτος) or Naupactus, is a town and a former municipality in Nafpaktia, Aetolia-Acarnania, West Greece, situated on a bay on the north coast of the Gulf of Corinth, 3 km (2 mi) west of the mouth of the river Mornos.

It is named for Naupaktos (Ναύπακτος, Latinized as Naupactus), an important Athenian naval station in the Peloponnesian War. As a strategically crucial possession controlling access to the Gulf of Corinth, Naupaktos changed hands many times during the Crusades and the Ottoman–Venetian Wars. It was under Venetian control in the 15th century, and came to be known by the Venetian form of its name, Lepanto. It fell to the Ottoman Empire in 1499 and was used as a naval station by the Ottoman Navy in the 16th century, being the site of the decisive victory by the Holy League in the Battle of Lepanto in 1571. Except for a brief period of Venetian control in 1687–1699, Lepanto remained under Ottoman control until Greek independence in 1829.
