The Basilica Papale di San Lorenzo fuori le mura is a Roman Catholic papal minor basilica and parish church, located in Rome, Italy. The Basilica is one of the Seven Pilgrim Churches of Rome and one of the five "papal basilicas", each of which was assigned to the care of a Latin Church patriarchate. The basilica was assigned to the Patriarchate of Jerusalem. The basilica is the shrine of the tomb of its namesake, Lawrence, one of the first seven deacons of Rome who was martyred in 258. Many other saints and Pope Pius IX are also buried at the Basilica, which is the centre of a large and ancient burial complex.

Basilicas are Catholic church buildings that have a designation, conferring special privileges, given by the Pope. Basilicas are distinguished for ceremonial purposes from other churches. The building need not be a basilica in the architectural sense. Basilicas are either major basilicas, of which there are four, all in the Diocese of Rome, or minor basilicas, of which there were 1,810 worldwide as of 2019.
