Corioli, an ancient Volscian city in Latium adiectum, taken, according to the Roman annals in 493 BC, with Longula and Pollusca, and retaken for the Volsci by Gaius Marcius Coriolanus, its original conqueror, who, in disgust at his treatment by his countrymen, had deserted to the enemy.

After this it does not appear in history, and we hear soon afterwards (443 BC) of a dispute between Ardea and Aricia about some land which had been part of the territory of Corioli, but had at an unknown date passed to Rome with Corioli.

The site is apparently to be sought in the North-Western portion of the district between the sea, the river Astura and the Alban Hills; but it cannot be more accurately fixed (the identification with Monte Giove, South of the Valle Aricciana, rests on no sufficient evidence), and even in the time of Pliny it ranked among the lost cities of Latium.
