Juan López Sanchez (16 January 1900 – 1972) was a Spanish construction worker, anarchist and member of the Confederación Nacional del Trabajo (CNT, National Confederation of Labor), and one of the founders of the Federación Sindicalista Libertaria.
During the Spanish Civil War (1936–39) he was Minister of Commerce under Francisco Largo Caballero.
After the war he spent several years in exile before returning to Spain where he lived without persecution and participated in the "vertical" trade union movement authorized by the dictatorship of General Francisco Franco.
