The Lanzo Valleys (in Italian Valli di Lanzo, in Piedmontese Valade ëd Lans) is a group of three valleys in the north-west of Piedmont in the Metropolitan City of Turin, Italy. They are located in the Graian Alps of Piedmont, between the Valle dell'Orco to the north and the Val di Susa to the south. Crossed by various streams which in each valley is called Stura and which flow into the river Stura di Lanzo, the valleys take their name from the town of Lanzo, located on an ancient glacial moraine at the end of the valleys.
