The Republican, Radical and Radical-Socialist Party (French: Parti républicain, radical et radical-socialiste) is a liberal and formerly social-liberal political party in France. It is also often referred to simply as the Radical Party (French: Parti radical), or to prevent confusion with other French Radical parties as the Parti radical valoisien (after its headquarters on the rue de Valois), abbreviated to Rad, PR, PRV, or historically PRRRS.
