The First of October Anti-Fascist Resistance Groups (Spanish: Grupos de Resistencia Antifascista Primero de Octubre, GRAPO) was a Spanish clandestine Marxist–Leninist group aiming for the formation of a Spanish Republican state.

The group was anti-capitalist, anti-imperialist, and strongly opposed Spain's membership in NATO.^[1]

GRAPO's last attack was in 2006. After having been fairly active in the late 1970s and early 1980s, a dwindling number of its militants along with police actions allowed Spanish officials to claim a number of times to have disbanded the GRAPO after the remaining militants were captured.^[2] According to the Spanish police, GRAPO was disbanded after six of its militants were arrested in June 2007^[3] but formally, the group has not announced its dissolution.^[4]

GRAPO is included in the European Union's list of terrorist organisations.^[5]
