Palazzo Sant'Agostino, Provincial government palace in Salerno, Italy.

Palazzo Sant'Agostino is a four-story, 24-metre-high building in central Salerno with a rectangular plan, an atrium and two small internal courtyards. Its neoclassical facade by Giuliano de Fazio, added in the early 19th century, has rustication on the ground floor and two columns at the entrance. A clock tower on the north side faces Piazza Cavour.

The building originated in 1309 as an Augustinian monastery before becoming a government facility during the Napoleonic period under Gioacchino Murat. War damage in 1943 destroyed part of one wing, prompting extensive reconstruction work in the following decade.

The halls inside served as spaces for official gatherings and provincial meetings over many decades. Visitors can see decorative emblems and symbols that reflect the administrative role this building has held for the region.

The building sits directly on the Lungomare Trieste, a main street in the city center that is easy to locate. Visitors can view the neoclassical facade and exterior details from the street, though interior access may be limited depending on administrative schedules.

The clock tower stands at the north corner of the building, where Via Duomo meets Via Roma, and its dial faces Piazza Cavour on the Lungomare Trieste, not the harbor itself. The tower was moved to this corner in 1928, when a third floor was added for the province.
