SC Wacker Leipzig was a German association football club playing in Leipzig, Saxony. The club was formed 24 February 1895 out of the merger of the school clubs "Concordia Leipzig" and "Saxonia Leipzig". "Wacker" was a founding member of the German Football Association (Deutscher Fussball Bund) in 1900.
The coming together of Concordia and Saxonia made Wacker the only founding member of Deutscher Fussball Bund.
