Becca di Nona (French: Pic de Nona) is a peak in the Graian Alps of the Aosta Valley in north-western Italy.

Together with Monte Emilius, it is one of the main mountains visible from Aosta looking southwards.

This mountain was known in the past as Pic de onze heures, that is to say "11 a.m. peak" in French, as the sun stands right on top of it at 11 am.

The hagiography of St Anselm written by his chaplain Eadmer records that, when he was a child, he had a mystical vision of God and his court on the mountain.

Every year a running race, the Becca di Nona Skyrace or Skyrace Ville d'Aoste, is organized starting from Émile Chanoux square in Aosta, arriving to the peak and returning to the city.
