The Palazzo della Cancelleria (Palace of the Chancellery, referring to the former Apostolic Chancery of the Pope) is a Renaissance palace in Rome, Italy, situated between the present Corso Vittorio Emanuele II and the Campo de' Fiori, in the rione of Parione. It was built 1489–1513 by Baccio Pontelli and Antonio da Sangallo the Elder<ref>FROMMEL, Christop. Architettura del Rinascimento Italiano. Milano, Skyra, 2009, p. 150-154''</ref> as a palace for Cardinal Raffaele Riario, Camerlengo of the Holy Roman Church, and is regarded as the earliest Renaissance palace in Rome. The Palazzo houses the Papal Chancellery, is an extraterritorial property of the Holy See, and is designated as a World Heritage Site.

He gifted the palace to his cousin, Cardinal Giulio de Medici (the future Pope Clement VII).

During the late 17th century Christina, former Queen of Sweden, resided here. During the Roman Republic of 1849 the parliament briefly sat here. In 2015, it was the residence of retired, and now deceased, Cardinal Bernard Law of Boston, United States. Architecture The Palazzo della Cancelleria was the first palazzo in Rome to be erected from the ground up in the new Renaissance style. Its long facade engulfs the small Basilica di San Lorenzo in Damaso, the Cardinal's titular church, that is to its right, with the palatial front continuing straight across it. The entrance to the Basilica is on the right side of the facade. The 5th-century basilica (its interior has been rebuilt) sits, like the Basilica di San Clemente among others, on a pagan Roman mithraeum. Excavations beneath the cortile'' from 1988 to 1991 revealed the 4th- and 5th-century foundations of the grand Basilica di San Lorenzo in Damaso, founded by Pope Damasus I, and one of the most
