Borgo is an Italian word, cognate with English burgh, German Burg, French bourg, that now usually means the new town outside the walls of an old town (the paese). Very often the borgo is a distinct frazione from the paese, and its name is that of the town with Borgo added, either before or after: for example, the lower town of Trevi is Borgo Trevi; the lower town of Cerreto di Spoleto is Cerreto Borgo.

Borgo (sometimes called also I Borghi), is the XIV historic district (rione) of Rome. It lies on the west bank of the Tiber, and has a trapezoidal shape. Its Coat of Arms shows a lion (after the name "Leonine City", which was also given to the district), lying in front of three mounts and a star.
