Mont Brouillard (4,069 m) is a mountain in the Mont Blanc massif in the Val d’Aosta, Italy, being a satellite peak on the south ridge of Mont Blanc. Though in French this name means “mountain of mist”, this toponym comes from Valdôtain Francoprovençal patois. According to Aostan botanist and scientist Joseph-Marie Henry, the word Broillà means “made of breuils“, Breuil meaning alpine marshy berm, as for Breuil in Valtournenche.
