Elaeonas or Elaionas (Greek: Ελαιώνας meaning olive grove 'the place where olives grow', before 1949: Τρυπιά - Trypia ) is a village and a community in the municipal unit of Diakopto, in the northern part of the Peloponnese peninsula, Greece. It is on the Gulf of Corinth, 3 km west of Diakopto and 9 km southeast of Aigio. The Olympia Odos (Greek National Road Α8) (Patras - Corinth - Athens) passes south of the village. The community consists of the villages Elaionas, Metochi and Terpsithea. The village lies between the river of Vouraikos and Selinountas in the foothills of Mount Marathia. According to Pausanias, travelers could visit the caverns of Heracles in those foothills. A small marked path off the Old National Highway leads you to these caves.
