Mongrassano (Arbëreshë Albanian: Mungrasana) is a town and comune in the province of Cosenza in the Calabria region of southern Italy, located 42 kilometers northwest of Cosenza.The town is part of the Comunità Montana Media Valle Crate, a regional association of municipalities.

The town's history dates back to at least the 12th century, when it was known by various names such as Mons Crasanus, Moncressano, Mocrasani, Montegrassano, or Magrosani.

The town's urban structure is typical of many settlements of Albanian origin in the region, characterized by circular streets, known as gijtonia.

Mongrassano saw an influx of Albanian political refugees either in 1459 or early in the 16th century, which significantly influenced its culture and development.

Over the years, the town changed hands, with the Gaetani family acquiring the territory in 1642, and later selling it to the Marquesses of Fuscaldo in 1688, who retained ownership until the end of the feudal system in 1806.
