Circus Renz (German: Zirkus Renz) is a 1943 German drama film directed by Arthur Maria Rabenalt and starring René Deltgen, Paul Klinger and Angelika Hauff.

It is a circus film, made as a deliberately escapist release at a time when the Second World War was starting to turn against Germany and its allies.

It premiered at Berlin's UFA-Palast am Zoo in September 1943.

It was made partly at the Babelsberg Studios in Berlin.

The film's sets were designed by the art director Ernst H. Albrecht.
