Heinz Kiwitz (September 4, 1910 – 1938) was a German artist. His woodcuts were in the German Expressionist style. An anti-fascist, he was arrested following the Nazis' seizure of power. He survived imprisonment in Kemna and Börgermoor concentration camps and was released in 1934. He went into exile in 1937, first living in Denmark, then in France, where he again began to fight Nazism. In 1938, he went to Spain to fight in the Spanish Civil War, where he apparently perished.
