Santi Marcellino e Pietro is a Neoclassical-style, Roman Catholic church in Imbersago, province of Lecco, region of Lombardy, Italy.
A church at the site was likely present by the 12th or 13th centuries. However, a map from 1721 shows the church with attached cloisters. In 1789, Luigi Canonica, putatively pupil of Giuseppe Piermarini, was commissioned to enlarge the church, and create a new facade.
The church has a single nave. The presbytery is separated from the rest of the nave by a marble balustrade. The main altar, in white marble, was designed and sculpted by Alessandro Verdi. The organ was built by the Serassi family.
