Socorro Rojo del P.O.U.M. ('POUM Red Aid') was a volunteer organization in Spain, active during the Spanish Civil War. The organization was set up by the Workers' Party of Marxist Unification (POUM), modelled after the Communist Party-led International Red Aid. All P.O.U.M. party members had to be members of the organization.
The organization issued the publication Socorro Rojo.
