Saint Agnes Outside the Walls (Italian: Sant'Agnese fuori le mura) is a titular church and minor basilica in Rome located on a slope descending from the Via Nomentana. The church stands above the Catacombs of Saint Agnes, where the saint was originally buried and which remain accessible from the church. A larger basilica of the same name was built nearby in the 4th century; its ruins can still be seen near Santa Costanza. The present church was constructed by Pope Honorius I in the 7th century and largely preserves its original structure. Notably, the apse mosaic depicting Saint Agnes, Honorius, and another unidentified pope remains mostly intact.
