The Crimson Circle (German: Der rote Kreis) is a 1929 British-German crime film directed by Frederic Zelnik and starring Lya Mara, Fred Louis Lerch, and Stewart Rome. The film is an adaptation of the 1922 Edgar Wallace novel The Crimson Circle in which Scotland Yard detectives battle a gang of blackmailers. A previous UK version was filmed in 1922.

The film, a co-production between British International Pictures and Efzet Film, was made in both a silent version and a sound version filmed in the Phonofilm sound-on-film system. In March 1929, this film and The Clue of the New Pin, filmed in the British Phototone sound-on-disc process, were previewed in London.
