A Conservatore of Rome (Italian: Conservatore di Roma)[a] was one of three magistrates in medieval Rome, dividing power on the model of the ancient Roman consuls.
Together with the Prior of the Caporioni, these three men formed the Roman Magistracy (il Magistrato Romano), the executive power in the city of Rome between the 13th century and the end of the papacy's temporal power in 1870.
The main tasks in which the Conservatori were involved were in accounting supervision of the Comune and to serve a special Tribunal for economic crimes.
They were in charge of the decision to confer the Roman citizenship to the newcomers.
The Conservatori were elected randomly for their temporary office amongst the Patrizi of the city.
