Junio Valerio Scipione Ghezzo Marcantonio Maria Borghese (6 June 1906 – 26 August 1974), 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.
