Montelibretti is a town and Italian: [[comune]] (municipality) in the Metropolitan City of Rome in the Italian region of Lazio, located about 30km (20miles) northeast of Rome on the slopes of Monti Sabini.
Montelibretti borders the following municipalities: Capena, Fara in Sabina, Fiano Romano, Monterotondo, Montopoli di Sabina, Montorio Romano, Moricone, Nerola, Palombara Sabina. The hamlet Borgo Santa Maria is a part of the town administratively.
The name derives from the presence of a Roman villa owned by Caius Brutius Presentis, Commodus' father-in-law. In the Middle Ages, starting from the 15th century, it was a fortress of the Orsini, who were succeeded by the Barberini and then by the Sciarra.
In 1867 it was the location of a battle between Garibaldine and Papal troops, in the course of the Battle of Mentana.
