The Independent Left (French: Gauche indépendante, GI) was a French parliamentary group in the Chamber of Deputies of France of the French Third Republic during the interwar period. It was not a political party but a technical group formed by independents and parties too small to form their own parliamentary group, including dissidents from the Communist, Socialist and Radical-Socialist parties, as well as left-wing regional parties and left-wing Catholics.
It provided a home to those republican independents and small parties who supported the Cartels des Gauches and the Popular Front. As such, its exact membership changed from legislature to another. It was thus similar but distinct to the right-of-centre Independents of the Left group, which gathered up the independents and small parties who in temperament were similar to the right wing of the Radical-Socialists and the centre-right Radical Left, but who refused to support the Cartel and Popular Front.
