The Reyran is a torrent of the Var department in Provence-Alpes-Côte d'Azur, France and a tributary of the Argens.

During the summer months, the river bed may present a series of isolated ponds that decrease in size by the day.

The bed of the Reyran is made of coarse sand and gravel up to 30–40 cm.

A flood of this type occurred in 2012 and destroyed the concrete ford located just downstream from the highway bridge, close to the ancient hamlet of Malpasset devastated in 1959.

[3] The Frejus runs north to south and empties into the Argens at the Naval Air Base of Frejus-Saint Raphael.
