Gabriele Adinolfi (Rome, 3 January 1954) is an Italian far right ideologue and essayist. He was one of the prominent characters of the 1970s extraparliamentary far right.
Adinolfi started his political activity in the years of student protests. In 1968 he was involved in the Roman Italian Social Movement scene, in particular he was active in the Filippo Anfuso section in via Livorno (next to Piazza Bologna).
From 1970 he began joining several far right extraparliamentary movements: the Fronte Studentesco, then Avanguardia Nazionale, Lotta di Popolo and, in the end, Alternativa Studentesca. Together with Giuseppe Dimitri and Roberto Fiore, in 1976, he is one of the founders of Lotta Studentesca in the bookshop of Walter Spedicato. In 1977 Lotta Studentesca becomes Terza Posizione, which eventually become one of the most important extraparliamentary far right movements.
In the investigations following the Bologna Massacre (and the discovery of explosives being smuggled by members of Terza Posizione in Rome during a casual control) an arrest warrant was issued on 28 August 1980 for Adinolfi, Fiore and other 26 far right exponents. Interrogations took place in Ferrara, Rome, Padua and Parma. On 23 September 1980 Terza Posizione was declared illegal, and another arrest warrant was declared, for the crime of subversive association.
As Adinolfi was found guilty of associative and ideologous crimes, he fled the country, and finally settled in France. He do however continue to travel back and forth from Italy, to follow the evolution of the far right scene.
In 1982 in Paris, Adinolfi collaborated in the realization of three numbers of the journals Terza Posizione and Dixie, the latter focusing on finance and power. In the same year, Adinolfi and Spedicato gave life to the Centro Studi Orientamenti e Ricerca ("Scholarship Center for Orientation and Research") in which they elaborate five political documents and ten years of trimonthly bulletins. Orientamenti e Ricerca stopped its publications in 1995 with the death of Spedicato.
