Agira (Italian: [aˈdʒiːra]; Sicilian: Aggira; Ancient Greek: Ἀγύριον, romanized: Agúrion) is a town and comune in the province of Enna, Sicily (southern Italy).

Agira stands on the site of the ancient Sicel city[4] of Agyrion (Ancient Greek: Ἀγύριον - Agyrion), or Agyrium, and Agyrina,[5] On the top of the mountain where the castle stands, excavations have brought to light buildings dated between the sixth and fourth centuries BC with the presence of polychrome plaster and remains of the mint for coins.

Diodorus Siculus was born here[6] and credits Heracles with the foundation of sacred precincts of Iolaus and of Geryon, and the creation of a nearby lake.

He was a contemporary of Dionysius the Elder, and with him successfully resisted the Carthaginian forces led by Mago when they invaded the territory of Agyrium in 392 BC.

The Pozzillo artificial lake lies near the town in a eucalyptus wood, and provides a habitat for a large variety of birds, and a way-stage for migrators.
