Feneos (Greek: Φενεός, Latin: Pheneus) is a village and a former municipality in Corinthia, Peloponnese, Greece.

[5] Catullus (Poem 68) mentions the seasonal flooding of the plain and says it was drained by an underground channel dug by Hercules during his Twelve Labors.

In the Aeneid, Evander's fond memories of a visit by Aeneas' father Anchises to Feneos are one factor in his decision to ally his Arcadian colonists to the Trojans.

[6] During the Greek Civil War, Communist guerillas turned the nearby monastery of St. George into a concentration camp and killing ground for those they deemed "reactionaries".

The concentration camp was well-organized for mass killings, with 6-7 resident killers that worked round the clock in busy times.
