The Palazzo Gabrielli-Borromeo is a palazzo in Rome, Italy, located between piazza di Sant'Ignazio and the Pantheon in the ancient Campus Martius and in the second sector of the present-day Colonna rione, not far from Via del Corso. The first palazzo on the site was built by the Gabrielli family, counts of Gubbio, whilst its second name derives from its rebuilding and redecoration by cardinal Vitaliano Borromeo for use by the Jesuits, following its purchase in 1774 for 32,000, scudi by Monte di Pietà.
