Cercle Proudhon was a national syndicalist political group in France. The group was inspired by Georges Sorel, Charles Maurras and a selective reading of anarchist theorist Pierre-Joseph Proudhon.

Georges Eugène Sorel was a French social thinker, political theorist, historian, and later journalist. He has inspired theories and movements grouped under the name of Sorelianism. His social and political philosophy owed much to his reading of Proudhon, Karl Marx, Giambattista Vico, Henri Bergson, and later William James. His notion of the power of myth in collective agency inspired socialists, anarchists, Marxists, and fascists. Together with his defense of violence, the power of myth is the contribution for which he is most often remembered.
