Mantzavinata (Greek: Μαντζαβινάτα) is a village in the southwest of Kefalonia island, Greece, where the famous Mantzavino Wine is sold.

Farming and agriculture are the main industry in Mantzavinata, although due to the nearby beaches, tourism also plays a significant part in the economy.

At Vazza, a Roman mosaic was found and is displayed today at the Archaeological Museum of Kefalonia.

World War II, and the complete destruction of the village in the 1953 Ionian earthquake increased emigration.

The name 'Mantzavinata' comes from the Italian words mangiare (eat) and vino (wine), -ata is the typical ending for places in Kefalonia.
