Orbassano (Italian: [orbasˈsaːno]; Piedmontese: Orbassan [ʊrbaˈsɑŋ]) is a comune (municipality) in the Metropolitan City of Turin in the Italian region Piedmont, located about 13 kilometres (8 miles) southwest of Turin.

Orbassano borders the following municipalities: Turin, Rivoli, Rivalta di Torino, Beinasco, Nichelino, Volvera, Candiolo, None.

The known origins of the city date back to the Roman conquest of Cisalpine Gaul, evidenced by two Imperial era tombstones found here in the second half of the nineteenth century.

In the twelfth century Orbassano came under the control of its northern neighbours the Lords of Rivalta, the Orsini family.

Sonia Gandhi was raised here, although she was born in Lusiana, near Vicenza.
