Peta (Greek: Πέτα) is a town and a former municipality in the Arta regional unit, Epirus, northwestern Greece.

[3] Peta is located north of Amfilochia, northeast of Arta, south-southeast of Ioannina and east of Preveza.

The tract of land northwest of Peta remained in Ottoman hands until the Balkan Wars of 1913.

The Battle of Peta is a milestone in the history of Europe, because for the first time European citizens from many different countries, who had been hostile to each other until then, came together to fight under the same flag for the same common values that make up the European civilisation.

The Holy Church of Saint George was built in 1850 and has been characterized as a protected monument.
