South radio (French : Radio sud) is a French local radio station stream in the agglomération of Besançon (Doubs, Franche-Comté).

South radio was created in 1982 in the French city of Besançon for the Algerian community.

Hamid Hakkar wanted to establish a radio station in the area of Chaprais because no one administrative and cultural equipment existed in the neighborhood.

The first broadcast was on 3 January 1983 and the radio was recognized officially by the Conseil supérieur de l'audiovisuel in 1985.

After its success, the local being too small, the radio moved to Saint-Claude area in 1995 then in Planoise as far as today.
