Otto Friedrich Wilhelm Stapel (27 October 1882 – 1 June 1954), was a German Protestant and nationalist essayist. He was the editor of the influential antisemitic monthly magazine Deutsches Volkstum from 1919 until its shutdown by the Nazis in 1938. After 1945, Stapel despised the new German Federal Republic and, in 1949, called for a boycott of the Bundestag elections. He died in Hamburg in 1954 at the age of 71, largely unnoticed from the public.
