Andreas Kleinlein (1864–1925) was a German anarchist. He came into contact with anarchist ideas through his travels to France. He was active in the musical instrument-maker union in Berlin and a founding member of the Free Association of German Trade Unions (FVdG), one of the most influential anarchists in the organization.
