Pioltello (Lombard: Pioltell [pjulˈtɛl]) is a comune (municipality) in the Metropolitan City of Milan in the Italian region Lombardy, located about 7 kilometres (4 mi) northeast of Milan.

Pioltello borders the following municipalities: Cernusco sul Naviglio, Vimodrone, Segrate, Rodano, Peschiera Borromeo, Vignate.

Pioltello is served by Pioltello-Limito railway station. Among the churches, is the baroque-style, Roman Catholic Chiesa della Immacolata.

Located about 6 kilometers east of Milan, the territory is between the SP ex SS 11 Padana Superiore (to the north, located between Cernusco sul Naviglio and Cassina de 'Pecchi) and the SP 14 Rivoltana (to the south, located between Rodano and Vignate) and is arranged along the north south axis, with an east west width of a couple of kilometers. This long and narrow stripe conformation is the result of the history of the city, born from the merger on 1 January 1870 of two up to that time independent municipalities: Pioltello and Limito. From the time until today, the territory between the two historic centers has been almost completely urbanized, with the birth of the Seggiano district.

The long and narrow strip is cut by several crossings: the SP 103 Cassanese between Pioltello, Vignate and the Ferdinandea railway, always between Limito and Vignate. The new Porta railway station is under construction, one of the three planned in the Milan area, together with Rogoredo and Rho-Pero. Pioltello is also the terminus of the S6 line of the Milan suburban railway service.

South of the SP 14 Rivoltana since the 70s the residential district of San Felice has risen, extending the urbanized area towards the south and thus bringing the Rivoltana within the urban fabric of the city even if only a small part (only 2 streets) is part of the municipality of Pioltello. In recent years, always south of the SP 14 Rivoltana, the new Malaspina locality has developed on the border with San Felice, which until a few years ago was only the seat of the Niccolò Machiavelli Liceo Scientifico, while now it has become a new and modern residential center. on the edge of the so-called Bosco della Besozza (one of the city parks). Since 2009, the Italian headquarters of the multinational have been transferred to this location3M, located first in nearby San Felice.

Despite the vicissitudes that Pioltello suffered, particularly in the 1960s and 1970s, with a very strong population growth and the birth of low-cost and low-quality residential districts, Pioltello still has large agricultural and green areas, which divide it from Milan and Segrate and bring it closer to the Municipalities of Martesana, of which it is geographically part.

Since 1999 Pioltello has acquired the title of city and the motto with which Pioltello currently presents itself is the city of three parks, where the three parks mentioned are the Parco delle Cascine (defined with a resolution by the former Province of Milan PLIS: Local Park of Supracomunale interest), the Trenzanesio Park (Villa Invernizzi) and the Bosco della Besozza, the latter owned by the municipality and on which one of the urban forests financed by the Lombardy Region is rising.
