The Alpes Graiae et Poeninae, later known as Alpes Atrectianae et Poeninae (officially Alpes Atrectianae et Vallis Poenina), was a small Alpine province of the Roman Empire created after the merging of the Alpes Poeninae (or Vallis Poenina) and the Alpes Graiae (or Alpes Atrectianae), probably during the reign of Claudius.
