Pleuron (Ancient Greek: Πλευρών, gen.: Πλευρῶνος; Greek: Πλευρώνα, Plevrona or Ασφακοβούνι, Asfakovouni) was a city in ancient Aetolia, Greece. The name refers to two settlements, the older of which was at the foot of between the river Acheloos and the river Evenos, and was mentioned by Homer in the Catalogue of Ships in the Iliad. The territory of Pleuron was called Pleuronia. The ruins of this more ancient city are north of the newer one and consist of a few remnants of Cyclopean walls.
