San Pietro Martire (Italian: "St. Peter, the Martyr") is a Roman Catholic church in Naples, Italy.

It is located directly across from the principal building of the University of Naples on the main street, Corso Umberto corner with Via Porta di Massa, near the port area.

The church belongs to the first wave of construction under the Angevin dynasty in Naples, which includes better-known structures such as the Maschio Angioino.

Construction on San Pietro Martire, dedicated to Saint Peter of Verona, was started in 1294 under Charles II of Anjou to provide a facility for the Dominican Order; the church and adjacent monastery premises were finished by 1343.

The area around the premises underwent drastic remodelling in 1900 as part of a massive urban renewal (Risanamiento) of Naples, and both church and monastery were damaged by bombing in World War II due to their proximity to the port of Naples, a target of bombing raids.

The church contains a number of ancient tomb monuments including members of the court of King Ladislaus of Naples.
