Jean-Marc Théolleyre (31 July 1924 – 12 June 2001) was a 20th-century French journalist.
Jean-Marc Théolleyre was convicted in 1983 by the Paris Court of Appeal for defamation, having suggested in his book Les néo-nazis (ed.
Messidor, 1982) that "Jean-Marie Le Pen professed neo-Nazi opinions".
The Court's judgment, inter alia, stated that "he did not exercise the caution, reserve and objectivity required by amalgamating or insinuating" (Paris Court of Appeal, 15 June 1983).
