Portuense is the 11th quartiere of Rome (Italy), identified by the initials Q.XI.

The toponym is also used to indicate the urbanistic area 15b, in the Municipio XV. The population of the urbanistic area amounts to 30.362 inhabitants.

There is also a suburbio (suburb) with the same name, identified by the initials S.VII.

Portuense is one of the first 15 Quartieri born in 1911 and officially established in 1921. It took its name from the ancient Via Portuense.

The quartiere is in the southern area of the town, close to the Aurelian Walls and to the river Tiber.

The territory of Portuense includes the urban zones 15B Ostiense and 15C Pian Due Torri, a great portion of the urban zone 16A Marconi as well as a little part of the urban zone 16D Gianicolense.

To the north, Portuense borders with Rione Trastevere (R. XIII), whose border is shortly marked by Piazza di Porta Portese. It also borders with Rione Testaccio (R.XX), from which is separated by the stretch of the Tiber between Ponte Testaccio and Ponte dell'Industria.

Eastward, the quartiere borders with Ostiense (Q.X) and with Europa (Q.XXXII), from which is separated by the stretch of the Tiber between Ponte dell'Industria and the Magliana Viaduct.

To the south-west, it borders with Suburbio Portuense (S. VII), whose border is marked by the Magliana Viaduct, by a short stretch of the Autostrada Roma-Fiumicino, by Via Salvatore Satta, Largo Giuseppe Petrelli, Via dell'Imbrecciato, Via Bolgheri, Via Riccardo Lombardi, and by another stretch of Via dell'Imbrecciato up to Via Portuense.

Westward, Portuense borders with Quartiere Gianicolense (Q.XII), whose boundary is defined by Via Portuense, Via Ettore Rolli and by another stretch of Via Portuense.

Main roads and squares of the quartiere are:

• Via della Magliana, connecting Portuense to the neighborhood of Magliana, which is comprised in Suburbio Portuense;
• Viale Guglielmo Marconi, a huge thoroughfare which connects the district to Quartiere Ostiense and to Via Cristoforo Colombo;
• Piazza della Radio, at the end of Viale Guglielmo Marconi;
