Anti-German is the generic name applied to a variety of theoretical and political tendencies within the left mainly in Germany and Austria. The Anti-Germans form one of the main camps within the broader Antifa movement, alongside the Anti-Zionist anti-imperialists, after the two currents split between the 1990s and the early 2000s as a result of their diverging views on Israel. The anti-Germans are a fringe movement within the German left: In 2006 Deutsche Welle estimated the number of anti-Germans to be between 500 and 3,000. The basic standpoint of the anti-Germans includes opposition to German nationalism, a critique of mainstream left anti-capitalist views, which are thought to be simplistic and structurally antisemitic, and a critique of antisemitism, which is considered to be deeply rooted in German cultural history. As a result of this analysis of antisemitism, support for Israel and opposition to Anti-Zionism is a primary unifying factor of the anti-German movement. The critical theory of Theodor Adorno and Max Horkheimer is often cited by anti-German theorists.

Antifa is a political movement in Germany composed of multiple far-left, autonomous, militant groups and individuals who describe themselves as anti-fascist. According to the German Federal Office for the Protection of the Constitution and the Federal Agency for Civic Education, the use of the epithet fascist against opponents and the view of capitalism as a form of fascism are central to the movement. The antifa movement has existed in different eras and incarnations, dating back to Antifaschistische Aktion, from which the moniker antifa came. It was set up by the then-Stalinist Communist Party of Germany (KPD) during the late history of the Weimar Republic. After the forced dissolution in the wake of Machtergreifung in 1933, the movement went underground. In the postwar era, Antifaschistische Aktion inspired a variety of different movements, groups and individuals in Germany as well as other countries which widely adopted variants of its aesthetics and some of its tactics. Known as the wider antifa movement, the contemporary antifa groups have no direct organisational connection to Antifaschistische Aktion.
