Fréjus (Occitan: Frejús, French pronunciation: [fʁe.ʒys]) is a commune in the Var department in the Provence-Alpes-Côte d'Azur region in southeastern France.
It neighbours Saint-Raphaël, effectively forming one town. The north of the commune forms part of the Estérel Massif.
On 2 December 1959, the Malpasset Dam, on the Reyran river above Fréjus, ruptured, killing over 400 people.
