George Sorel (1847-1922) was a French philosopher and theorist of anarchosyndicalism.

Sorel had been a Marxist in the 1890s. He tried to fill in what he believed were gaps in Marxist theory but ultimately created a variation of the ideology. He rejected Marxist theories of historical materialism, dialectical materialism, and internationalism. Sorel came to favour the anarcho-communism of Proudhon and Bakunin. He was heavily influenced by Henri Bergson who developed the importance of myth and demolished scientific materialism.

Sorel rejected those Marxists who believed in inevitable and evolutionary change, preferring more "direct action" approaches. These approaches included general strikes, boycotts, sabotage, and constant disruption of capitalism with the goal being to achieve worker control over the means of production. Sorel's belief in the need for a deliberately-conceived "myth" to sway crowds into concerted action was put into practice by mass fascist movements in the 1920s.

He echoed the Jacobin tradition in French society that held that the only way for change to occur was through the application of force. Sorel praised Charles Maurras, Action Française and Lenin for attacking bourgeois democracy.

Sorel had ties of friendship to Antonio Labriola and wrote a preface to the French translation of Labriola's Essays on the Materialist Conception of History.
