The Graian Alps (Latin:: Alpes Graiæ ; French: Alpes grées [alp ɡʁe]; Italian: Alpi Graie [ˈalpi ˈɡraːje]) are a mountain range in the western part of the Alps, and the name of an Ancient Roman province.

The name Graie comes from the Graioceli Celtic tribe, which dwelled in the area surrounding the Mont Cenis pass and the Viù valley. Other sources claim that the name comes from the Celtic Graig meaning "rock" or "stone", literally the Rocky Mountains.

The name of the Antic Rome province comes from the local celtic god Graius.

The Graian Alps are located in France (Auvergne-Rhône-Alpes), Italy (Piedmont and the Aosta Valley ), and Switzerland (western Valais).

The French side of the Graian Alps is drained by the river Isère (Tarentaise valley) and its tributary Arc (Maurienne valley), and by the Arve .
