Jean-François Thiriart, Belgian politician (b. 1922)
Jean-François Thiriart (22 March 1922, Brussels – 23 November 1992) was a Belgian political theorist.

Coming from a left-wing background, during the Second World War he was a collaborator with the Nazi Third Reich, as a result of which he served a prison sentence. In the 1960s, he founded and directed the transnational Jeune Europe (Young Europe) movement. He was the theorist of European national communism, a synthesis of revolutionary nationalism and Pan-European nationalism, a form of revolutionary nationalism transposed up to the scale of Europe as a unitary state.
