L'Action française, organ of Integral nationalism, was a royalist French newspaper founded in Paris on 21 March 1908.

The newspaper succeeded the Revue d'Action française of Henri Vaugeois and Maurice Pujo.

Based on Rue de Rome in Paris, its director was Charles Maurras, the leader of the monarchist Action française movement.

Uniting collaborators from various nationalist and traditionalist movements, the newspaper became the crucible for the major currents of far-right ideology in France during the 1930s.

Through denunciation and personal attacks, its journalists, led by Léon Daudet, conducted intense royalist and anti-republican propaganda during World War I and the interwar period.
