Arijský boj ("Aryan Struggle") was a pro-Nazi Czech-language weekly tabloid newspaper published between May 1940 and May 1945 in the Protectorate of Bohemia and Moravia. Inspired by Der Stürmer, the newspaper made antisemitism its main theme and was also critical of the Czechoslovak government-in-exile. Denunciations published by the newspaper contributed to the isolation of Jews during the first years of the Holocaust in Bohemia and Moravia.
