The Communist Youth Union of Spain (Spanish: Unión de Juventudes Comunistas de España, UJCE; also simply the Communist Youth) is a Marxist-Leninist youth political organization that fights for the interests of the working class and its youth, it was formed by young communists in the Spanish state. It serves as the youth organization of the Communist Party of Spain, although since June 2023, this relationship has been suspended due to internal tension and attempts at intervention by the PCE towards the UJCE's structure.
