The German Society for Racial Hygiene (German: Deutsche Gesellschaft für Rassenhygiene) was a German eugenic organization founded on 22 June 1905 by the physician Alfred Ploetz in Berlin. Its goal was "for society to return to a healthy and blooming, strong and beautiful life" as Ploetz put it. The Nordic race was supposed to regain its "purity" through selective reproduction and sterilization. The society became defunct after World War II.
