Dora Baltea (Italian: [ˈdɔːra ˈbaltea]) or Doire Baltée (French: [dwaʁ balte]) (Latin: Duria maior or Duria Bautica;Arpitan: Djouire (Valdôtain); Piedmontese: Deura Bàotia), is a river in northern Italy. It is a left-hand tributary of the Po River and is about 170 kilometres (110 mi) long.

It originates by Mont Blanc as the confluence of the Dora di Ferret, fed by the Pré de Bar Glacier in Val Ferret, and the Dora di Veny, fed by the Miage Glacier in Val Veny.

As it crosses the Aosta Valley, the Dora Baltea flows through the city of Aosta (where the Buthier runs into it) and near all the main cities of the lower Aosta Valley: Châtillon, Saint-Vincent, Verrès and Pont-Saint-Martin. After it enters Piedmont, it passes through the city of Ivrea and a good part of Canavese, gets from its right hand the waters of the Chiusella and reaches the Po at Crescentino, a little downstream from Chivasso.
