Gefyra (Greek: Γέφυρα meaning "bridge") is a settlement in the municipality of Megalopoli, Arcadia, Greece.

The Greek National Road 7 (Corinth - Tripoli - Kalamata) passes south of the village.

There are large open-pit lignite mines to the northwest of the village.

The heroic 12 are remembered by a marble monument in the village square next to the Church of St. George.

Gefyra suffered damage from the 2007 Greek forest fires.
