Santa Susanna

The Church of Saint Susanna at the Baths of Diocletian (Italian: Chiesa di Santa Susanna alle Terme di Diocleziano) is a Roman Catholic parish church located on the Quirinal Hill in Rome, Italy. There has been a titular church associated to its site as far back as AD 280. The current church was rebuilt from 1585 to 1603 for a monastery of Cistercian nuns founded on the site in 1587, which still exists there.

The church served as the national parish for residents of Rome from the United States from 1921 to 2017, during which period it was assigned to the care of the Paulist Fathers, a society of priests founded in the United States.
