The Sassi–Superga tramway is a steep grade railway line in the city of Turin in northern Italy. Managed by Gruppo Torinese Trasporti, it connects the Turin suburb of Sassi to the Basilica of Superga at an altitude of 672 m (2,205 ft). The lower station is situated at an altitude of 225 m (738 ft) a.s.l., the upper at 650 m (2,130 ft). From here, high in the hills facing the city across the River Po, a panorama of Turin is visible against a backdrop of the Alps. Intermediate stops are located at Prima Galleria, Raddoppio, and Pian Gambino.

The Gruppo Torinese Trasporti (GTT) is a public benefit corporation responsible for public transportation in the provinces of Alessandria, Cuneo, Asti and the Metropolitan City of Turin. It was created in 2003 from the merge of ATM and SATTI, the latter responsible for railway connection in the province of Turin as well as for the Turin metro. GTT is now wholly owned by the Turin City Hall.
