Palazzo dell'Anagrafe, Rationalist palace in Ripa district, Rome, Italy.

Palazzo dell'Anagrafe is a rectangular rationalist building on Via Luigi Petroselli, between Via di Ponte Rotto and Via del Foro Olitorio, in Rome's Ripa district. It has a main entrance on Via Petroselli and a staff entrance on Lungotevere dei Pierleoni. A marble plaque on the main facade shows the Capitoline wolf and commemorates the building's 1939 inauguration.

The first stone was laid on 21 April 1936 in the presence of Benito Mussolini, after the area's medieval quarter and the Hospice of Santa Galla were demolished. Architects Ignazio Guidi, Cesare Valle and Vincenzo Fasolo designed the building for the Governatorato di Roma, and work continued until 1939. A marble plaque on the main facade commemorates the 1939 inauguration and still bears Mussolini's name with the title duce, alongside governor Piero Colonna.

The wall decoration Forma Urbis (Plan of Rome), designed by Duilio Cambellotti in 1938, measures 440 cm high and 330 cm wide and is made of veined yellow marble and mosaic. The building also holds Orfeo Tamburi's fresco Carnevale Romano. The marble plaque on the main facade bears a bas-relief of the Capitoline wolf and an inscription commemorating the 1939 inauguration, which still names Benito Mussolini as duce and Piero Colonna, governor of Rome from 1936 to 1939.

The building is located at Via Luigi Petroselli 50 and serves as a municipal center where citizens obtain personal documents and administrative services. Visitors should know this is an active government office with standard working hours and procedures.

During excavation for the building, workers uncovered remains of ancient warehouses from Rome's river port hidden beneath the construction site. These discoveries revealed that the location had once served as a major trading and goods distribution hub.
