Cesano is the 52nd zona of Rome, Italy, identified by the initials Z. LII. It takes its name from the small medieval village of Cesano di Roma, on the Via Cassia, which is located within the Municipio XV, 27 km from Rome proper.

The village of Cesano occupies a 240 m hill surrounded by the Monti Sabatini, near the Lakes of Bracciano and Martignano and near the now dried Lakes Stracciacappa and Baccano. It was a frazione of Campagnano di Roma until 1923, when at the request of the locals it was annexed to Rome (R.D. 3247 of December 23, 1923).

The most relevant holy day is the Holy Crucifix procession, which is held every September 14 since 1508.

Cesano is home to the Infantry School of the Italian Army and of the Casaccia Research Center of ENEA.

The zone is in the northern part of the municipality of Rome, in the Agro Romano. A large portion of it falls under the Regional Natural Park of Bracciano-Martignano and shares the eastern border with the Regional Park of Veii.

The zone is near to the ancient towns of Galeria [it] and Veii and to the ancient Via Clodia.

The zone borders, to the north, with the municipality of Campagnano di Roma; to the north-west, it also borders with the municipality of Anguillara Sabazia.

Eastward, Cesano shares a border with the municipality of Formello.

To the south, the zone borders with Zona La Storta (Z. LI), from which is separated by the Rio Galeria and by Via di Baccanello, up to Via Cassia. Southward, the zone also borders with Zona Santa Maria di Galeria (Z. XLIX), from which is separated by the stretch of Via Braccianese between the Rio Galeria and the Fosso Pietroso.
