The Pennine Alps French: Alpes Pennines, German: Walliser Alpen, Italian: Alpi Pennine, Latin: Alpes Poeninae), sometimes referred to as the Valais Alps, are a mountain range in the western part of the Alps. They are located in Italy and Switzerland (Valais).

The Alpes Graiae et Poeninae, later known as Alpes Atrectianae et Poeninae, was a small Alpine province of the Roman Empire created after the merging of the Alpes Poeninae and the Alpes Graiae, probably during the reign of Claudius. Comprising the modern Canton of Valais (Switzerland), the Tarantaise Valley (France), and the Aosta Valley (Italy), it was one of the three provinces straddling the Alps between modern France and Italy, along with the Alpes Maritimae and Alpes Cottiae.
