The Revolutionary Antifascist Patriotic Front (Spanish: Frente Revolucionario Antifascista y Patriota, sometimes also Frente Revolucionario Antifascista y Patriótico;[1] Catalan: Front Revolucionari Antifeixista i Patriota; FRAP) was a radical Spanish anti-Francoist, Marxist–Leninist revolutionary organization that operated in the 1970s.

[citation needed] In January 1971, shortly after Julio Álvarez del Vayo dissolved the largely inactive Spanish National Liberation Front (FELN), a coordinating committee for the creation of a revolutionary, antifascist and patriotic front (FRAP) began operating both in the universities of the largest cities in Spain (Valencia, Barcelona and Madrid) and among manufacturing workers of the main industrial regions as a still modest opposition movement against Francoist Spain.

That Coordinating Committee (Comité Coordinador) was formed by Raúl Marco (Julio Fernández), Elena Odena (Benita Benigna Ganuza Muñoz) and Eladio Zújar (Lorenzo Peña) from the Communist Party of Spain (Marxist–Leninist), as well as Alberto Fernández and Julio Álvarez del Vayo from the Spanish National Liberation Front (FELN).

[2] After the establishment of the FRAP proper, it initiated a more serious career of coordinating efforts with the aim of creating unrest in the universities and factories and motivating Spanish students and manual workers to begin an insurgency.

[4] After its success, the following year on 1 May 1974, when FRAP called for a demonstration in the largest universities against the Francoist State the response of the Spanish students was forthcoming.

FRAP's reaction in March was to initiate its 'armed phase' (fase armada) with the establishment of a 'military branch' (rama militar), a proposal that had been put forward by Álvarez del Vayo months before he died in exile in Geneva.

In 1982 during the first Spanish Socialist Workers' Party government under Felipe González an amnesty was granted to FRAP militants by Royal Order.
