Mount Kyllini or
Mount Cyllene (;
Greek: Κυλλήνη , ; sometimes Ζήρια, ), is a
mountain on the
Peloponnesus peninsula in
Greece, famous for its association with the god
Hermes. It rises to above

Arcadia and
Achaea—in the northeast of Arcadia, and entirely within modern
Corinthia. It is located west of Corinth, northwest of
Stymfalia, north of
Tripoli, and south of
Derveni.
