Bund Deutscher Osten (BDO) was a German Nazi organisation founded on 26 May 1933. The organisation was supported by the Nazi Party. The BDO was a national socialist version of German Eastern Marches Society, which was closed down by the Nazis in 1934. Reichsleiter of Bund Deutscher Osten between 1933–1937 was Theodor Oberländer.
In May 1933, when Passau founded its own association, school superintendent Wilhelm Leidl became its leader.
