The Golpe Borghese was a failed Italian coup d'état allegedly planned for the night of 7 or 8 December 1970. It was named after Junio Valerio Borghese, wartime commander of the Decima Flottiglia MAS and a hero in the eyes of many post-War Italian fascists. The coup attempt became publicly known when the left-wing journal Paese Sera ran the headline on the evening of 18 March 1971: Subversive plan against the Republic: far-right plot discovered.

Junio Valerio Scipione Ghezzo Marcantonio Maria Borghese, nicknamed The Black Prince, was an Italian Navy commander during the regime of Benito Mussolini's National Fascist Party and a prominent hardline neo-fascist politician in post-war Italy. In 1970, he took part in the planning of a neo-fascist coup, dubbed the Golpe Borghese, that was called off after the press discovered it; he subsequently fled to Spain and spent the last years of his life there.
