Monte Emilius (French: Mont Émilius) (3,559 m) is a mountain of the Graian Alps in Aosta Valley , north-western Italy. Located just above the town of Aosta, from where it is visible looking southwards behind the lower Becca di Nona , it is usually climbed starting from the ski resort of Pila, at a height of 1,870 m.

This mountain was formerly known as Pic de dix heures, meaning "10 a.m. peak" in French, as the sun stands right on top of it at 10am, or even as Pic Chamosser or Pic Chamoisier. In 1839 the priest Georges Carrel (later prior of the Collegiate church of Saint Ursus ) climbed the peak with a 14-year-old girl named Émilie Argentier, the daughter of the mountaineer and doctor Auguste Argentier (1830-1874) from Cogne , in order to promote mountaineering. The peak was thus named after her.
