The Basilica of St. Mary of the Angels and of the Martyrs (Latin: Beatissimae Virginis et omnium Angelorum et Martyrum, Italian: Santa Maria degli Angeli e dei Martiri) is a Catholic titular minor basilica and former Carthusian conventual church in Rome constructed in the ruined frigidarium and tepidarium of the Roman Baths of Diocletian in the Piazza della Repubblica.

It was constructed in the 16th century following an original design by Michelangelo Buonarroti. Other architects and artists added to the church over the following centuries. During the Kingdom of Italy, the church was used for religious state functions.
