The Mani Peninsula, also known as Maina, is a region in Greece. The Mani is the central peninsula of the three which extend southwards from the Peloponnese in southern Greece. To the east is the Laconian Gulf, to the west the Messenian Gulf. The peninsula forms a continuation of the Taygetos mountain range, the western spine of the Peloponnese.
The terrain is mountainous and inaccessible. The name "Mani" is thought to have originally meant "dry" or "treeless." Until recent years many Mani villages could be reached only by sea. Today a narrow and winding road extends down the west coast from Kalamata to Areopoli, but on the east coast there is no substantial road south of Gytheio.
