Parnon or Parnonas (Greek: Πάρνων/Πάρνωνας) or Malevos (Μαλεβός) is a mountain range, or massif, on the east of the Laconian plain and the Evrotas Valley.

Its summit offers panoramic views of southeastern Arcadia and South Kynouria and much of Laconia that includes the northern and the central portions and reaches as far as the Taygetos mountains.

Between the pass and Kounoupia to the south is 22 km (14 mi) of central Parnon, lower in altitude than the northern.

The remaining 38 km (24 mi), even lower in altitude but still mountainous, runs from Kounouria to the sea at Epidaurus Limera, which is in Monemvasia.

In addition to the range of Parnon, two forelands can also be defined, east and west.
