The Radical-Socialist Party Camille Pelletan (French: Parti radical-socialiste Camille Pelletan, PRS-CP) was a social liberal party in France founded in 1934 at the Clermont-Ferrand Congress of the Radical-Socialist Party as a reaction to the participation of Radicals in the right-wing Gaston Doumergue cabinet.
The PRS-CP was led by Gabriel Cudenet but never achieved any lasting success.
In fact, only 3 parliamentarians identified with the PRS-CP in the 16th legislature (1936–1940).
Most members rejoined the Radical Party post-war.
