Caivano is a city and comune (municipality) in the Metropolitan City of Naples in the Italian region Campania, located about 14 km northeast of Naples.

There are remains of an ancient Roman theater in Casolla.

Caivano was the first capital of Old Atella; it was replaced by Frattamaggiore.

Caivano has been heavily damaged by the waste traffic of the Camorra.

The town's outskirts are one of the most contaminated areas in Europe.
