San Giovanni dei Fiorentini, Rome. San Giovanni dei Fiorentini is a minor basilica and a titular church in the Ponte rione of Rome, Italy.

Julius II's successor, the Florentine Pope Leo X de' Medici initiated the architectural competition for a new church in 1518 on the site of the old church of San Pantaleo.
