Ludwig Schwamb (30 July 1890 in Undenheim – 23 January 1945 in Berlin) was a social-democratic jurist and politician who fought against the Nazi dictatorship in Germany as a member of the Kreisau Circle motivated by his Christian beliefs, and as a close colleague of Wilhelm Leuschner, which led to his execution as a resistance fighter. There were also contacts with other important opponents of the Nazi régime.
