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.

The Turin tramway network is an important part, along with the Turin Metro, of the public transport network of the city and comune of Turin, in the Piedmont region, northwest Italy.
