Europe-Action was a far-right and euro-nationalist magazine and movement, founded by Dominique Venner in 1963 and active until 1966. Distancing itself from pre-WWII fascist ideas such as anti-intellectualism, anti-parliamentarianism and traditional French nationalism, Europe-Action promoted a pan-European nationalism based on the "Occident"—or the "white peoples"— and a social Darwinism escorted by racialism, labeled "biological realism". These theories, along with the meta-political strategy of Venner, influenced young Europe-Action journalist Alain de Benoist and are deemed conducive to the creation of GRECE and the Nouvelle Droite in 1968.

In his 1962 manifesto Pour une critique positive ("For a Positive Critique"), written while he was in prison, former Jeune Nation member Dominique Venner rejected the myth of a coup de force, convinced that political revolution was impossible before a cultural revolution occurred. He believed that this cultural transformation could be achieved by publicly promoting nationalist ideas until they gained widespread support. Venner held that both intellectual persuasion and violence had their roles, but his movement needed to prioritize ideas over action. He also sought to remove the "old ideas" associated with pre‑World War II nationalism and fascism—such as anti-parliamentarianism, anti-intellectualism, and a form of patriotism limited solely to the nation-state.

The text became influential in nationalist circles, with François Duprat comparing For a Positive Critique to Lenin's What is to be Done?, a political pamphlet written 16 years before the Bolshevik Revolution. These nationalists maintained an ambiguous view of Nazism; Europe-Action, for example, quoted Maurice Bardèche as saying that "next to genial intuitions, Hitler made mistakes," attributing these errors to a "lack of established doctrinal foundations."

The group was further influenced by the Manifesto of the Class of '60, published three years before Europe-Action was founded. In that manifesto, the pro-colonial founders of the Federation of Nationalist Students (FEN) committed themselves to "action of profound consequence", as opposed to the "sterile activism" of mere street violence that Jeune Nation had promoted in the 1950s. Although Europe-Action members remained deeply committed to the cause of French Algeria, they also recognised the emerging world shaped by decolonisation and the consolidation of the French Fifth Republic. As a result, they sought to develop a radical right ideology based on elements beyond Vichy nostalgia and Catholic traditionalism.

Europe-Action was launched in January 1963 by Dominique Venner as a nationalist movement, accompanied by a magazine of the same name. Soon after its launch, Alain de Benoist and François d'Orcival joined the publication as journalists. Initially, Jacques Ploncard d'Assac contributed to the magazine, but he soon repudiated its anti-Christian stance and left in August 1963. The magazine was published by Société de Presse et d'Édition Saint-Just, a company founded in November 1962 by Venner, Suzanne Gingembre (the wife of former OAS treasurer Maurice Gingembre), and Jacques de Larocque-Latour, a racist caricaturist. Pierre Bousquet, a former member of the Waffen-SS, later became part of the company.

In 1964, Alain de Benoist took over as editor-in-chief of the weekly Europe-Action hebdomadaire. Along with the Federation of Nationalist Students, Europe-Action supported the far-right presidential candidacy of Jean-Louis Tixier-Vignancour in 1965 through the Tixier-Vignancour Committees. Following a dispute between Occident leader Pierre Sidos and campaign director Jean-Marie Le Pen, Europe-Action volunteers stepped in to support Tixier-Vignancour by joining his Comité Jeunes ("Youth Committee"). Venner's movement also mobilised its militant base to organise demonstrations against Algerian immigration.

From June 1965 to 1966, Jean Mabire served as redactor-in-chief of Europe-Action. After Tixier-Vignancour’s electoral defeat, key members of Europe-Action founded the European Rally for Liberty (REL) in 1966, in collaboration with young nationalists from the Federation of Nationalist Students. During the campaign, Europe-Action hebdomadaire became the organ of the REL before being replaced by a short-lived magazine titled L'Observateur Européen. The REL managed to field only 27 candidates during the 1967 legislative election, garnering just 2.58% of the vote, a failure often seen as paving the way for the creation of the ethno-nationalist think tank GRECE and the evolution of Nouvelle Droite meta-politics.

The magazine released its final issue in November 1966 following the bankruptcy of its publishing house, and Europe-Action ceased to exist in the summer of 1967 after an unsuccessful attempt to revive the publication. At its peak, the magazine had an estimated circulation of between 7,500 and 10,000 copies. Its symbol was a hoplite helmet.
