Cascia (Italian pronunciation: [ˈkaʃʃa]) is a town and comune (municipality) of the Italian province of Perugia in a rather remote area of the mountainous southeastern corner of Umbria.

The modern territory of Cascia was the home of the Roman settlement of Carsulae, destroyed in the 1st century BC by an earthquake.

In the Middle Ages it was sacked by the Byzantines and the Lombards, and was later a fief of the Trinci family.

The town also is home to the frescoed 14th-century church of Sant’Antonio Abate.
