The Evinos River or Evenus River (Greek: Potamos Evinou) is a river that flows entirely in the Aetolia-Acarnania prefecture. The river begins near the four boundaries area of the Aitoloakarnania, Evrytania, Phthiotis and Phocis in the Vardousia mountains, the length is about 60 to 70 km. The river was first mentioned in Homeric times and was known in the ancient times. It now empties into the reservoir of Lake Evinos, that is about 10 km² and eliminated a village. The river flows into the forested valley and into the populated areas, it empties into the Gulf of Patras east of the Acheloos near a tall mountain. Evinochori owes its name to its nearby river. The GR-5/E55 (Antirrio - Agrinio - Ioannina) runs over the river.
