The Church of Benedictines (Italian: Chiesa delle Benedettine) and its attached convent are a Baroque-style Roman Catholic church and monastery, located in central Piacenza, Emilia Romagna region, Italy.

The church and the Benedictine convent were built by Ranuccio II Farnese, Duke of Parma as a result of a vow he made, to build a church if his wife, Maria d'Este, were cured of an illness.

Initially dedicated to the Immaculate Conception of Mary, the complex was designed in 1677 by the court architect Domenico Valmagini, and was consecrated on August 31, 1681.

[1] The interior quadratura decoration was made by Ferdinando Bibiena.

The church has a Greek cross plan surmounted by an octagonal drum on which stands a bronze-pleated dome covered in lead and adorned with a roof lantern, surmounted in turn by the Farnese Lily.
