Santa Maria Assunta or St Mary of the Assumption is a Romanesque-style church in Assergi, central Italy.

The church was erected in the 12th century, originally part of a larger monastery founded by Saint Equizio.

The 15th-century white stone facade is simple, with a portal with a rounded tympanum, surmounted by a rose window.

There are several Renaissance-style frescos and a crypt, which is from the ancient church of San Franco of Assergi, the patron saint of the town.

The crypt is dug from the rock and contains three naves; the medieval reliquary once on this altar putatively held the relics of the saint.
