Rion is the northernmost municipal unit of the Peloponnese peninsula. It stretches along the southeastern coast of the Gulf of Patras, about 7 km northeast of Patras city centre. The nearby Strait of Rio, crossed by the Rio–Antirrio bridge, separates the Gulf of Patras from the Gulf of Corinth to the east. The town is dominated by the Panachaiko mountain to the southeast.
The town centre is also known as Agios Georgios Riou. This is where the Rio railway station, on the line from Patras to Corinth, is located. The quarter Kastellokampos lies to the southwest of the centre. The ferry terminals, with services to Antirrio, are in the north, on both sides of the Rio–Antirrio bridge. There is a large fortress with bastions next to the bridge. The campus of the University of Patras and the hospital lie in the southeast, across the Greek National Road 8A. There are sandy beaches along the coast, and a port north of town centre.
The municipal unit Rio is subdivided into the following communities (constituent villages in brackets):
The name Rio (and its older form Rhion) derives from the Greek ῥίον (rhion), generally meaning "jutting part", perhaps from ῥίς (rhis), meaning "nose", but also "spur of land". The earliest attested form of the word is the Mycenaean Greek 𐀪𐀍, ri-jo, written in Linear B syllabic script.
The site of Rio has been a strategic point since antiquity. Early 19th century, there stood an old Turkish castle (the "Castle of the Morea") at the cape, with a small settlement outside its walls.
