The Democratic and Socialist Union of the Resistance (French: Union démocratique et socialiste de la Résistance, UDSR) was a French political party founded after the liberation of France from German occupation, mainly active during the Fourth Republic (1947–58). It was a loosely organised "cadre party" without mass membership. Its ideology was vague, including a broad diversity of different political convictions, and it was variously described as left-wing, centrist, and even conservative. It was decidedly anti-communist and linked with the Paix et Liberté ("Peace and Liberty") movement. The UDSR was a founding member of the Liberal International in 1947.
