Ivrea (; ; ; ) is a town and "comune" of the Metropolitan City of Turin in the Piedmont region of northwestern Italy. Situated on the road leading to the Aosta Valley (part of the medieval Via Francigena), it straddles the Dora Baltea and is regarded as the centre of the Canavese area. Ivrea lies in a basin that in prehistoric times formed a large lake. Today five smaller lakes — Sirio, San Michele, Pistono, Nero and Campagna — are found in the area around the town.
