San Giacomo John Augusta - Baroque church in Rome, located on the Via del Corso, just three blocks south of the Piazza del Popolo in the Campo Marzio. Next to it stands the church of Gesu e Maria.

The first church on the site was built in the 14th century next to the hospital for the terminally ill (Incurabili) - it was called San Giacomo degli Inkurabili. A prefix "John Augusta" was added later, because of the Mausoleum of Augustus, located nearby.

That first church and the hospital were created in 1339 on the initiative of Cardinal Giovanni Colonna. By the early 16th century, the hospital was abandoned, but after a few decades, was re-opened under the patronage of the two religious orders. It was assumed that it will contain the patients with syphilis. Pope Nicholas V transferred to the jurisdiction of the Florentine Hospital of Cardinal Antonio Maria Salviati, who was the initiator of the reconstruction of the church. The oval in the plan structure has been completely redesigned for the project by Francesco da Volterra. Reconstruction began in 1592 and ended in 1600 already under the supervision of the architect Carlo Maderno, who worked on the facade and interior of the church.

The church interior is remarkable stucco reliefs and French sculptor Pierre Le Gros the Younger, paintings by Giuseppe Passero work mannerist painter Cristoforo Roncalli and other works of art.
