Val Melaina is the 1st Italian: [[Zones of Rome|zona]] of Rome, identified by the initials Z. I, lying north of the city centre and covering an area of 6.2447 km².
The classic 1948 film Bicycle Thieves[2] and Luigi Zampa's Italian: [[Il medico della mutua]] (1968) were shot in Val Melaina.
Val Melaina is in the northern part of the city, inside the Grande Raccordo Anulare. The boroughs of Nuovo Salario and Prati Fiscali are located within this zone.
The territory of Val Melaina includes the major part of the urban zone 4B Val Melaina, a little part of the urban zone 4E Serpentara and the southern part of the urban zone 4L Aeroporto dell'Urbe.
Northward, the zona borders with Castel Giubileo (Z. II), from which is separated by the countryside, between the river Tiber and Via Pian di Scò, by Via Pian di Scò itself, then by Via Gaetano Martino, Via Giacomo Brodolini and Viadotto Antonio Segni.
To the east, Val Melaina borders with Casal Boccone (Z. IV), whose boundary is marked by the stretch of Via delle Vigne Nuove between Viadotto Antonio Segni and Via Monte Resegone. To the south-east, it borders with Quartiere Monte Sacro (Q. XVI), from which is separated by Via Monte Resegone, Via Monte Massico, Via di Valle Melaina, Piazzale Jonio and Via dei Prati Fiscali up to Ponte Salario.
Southward, Val Melaina shares a border with Quartiere Parioli (Q. II), which is outlined by the stretch of the river Aniene, between Ponte Salario and the Tiber.
Westward, the zona borders with Quartiere Tor di Quinto (Q. XVIII) and with Zona Grottarossa (Z. LVI): the boundary is marked by the river Tiber.
Streets and squares of Val Melaina are chiefly named after Italian politicians and, particularly in the borough of Nuovo Salario, after towns in Tuscany. Odonyms of Val Melaina can be categorized as follows:
