The Kampfgruppe gegen Unmenschlichkeit (KgU) (German for "Combat Group against Inhumanity") was a German anti-communist resistance group based in West Berlin. It was founded in 1948 by Rainer Hildebrandt, Günther Birkenfeld and Ernst Benda and existed until 1959. Rainer Hildebrandt would a few years later establish the legendary Checkpoint Charlie Museum.
