Rasputin, the Holy Sinner (German: Rasputins Liebesabenteuer) is a 1928 German silent film directed by Martin Berger and starring Nikolai Malikoff, Diana Karenne and Erwin Kalser. The film was also released as Rasputin, the Holy Devil and Rasputin's Amorous Adventures. Director Berger made Rasputin into a sympathetic peasant character who was "exploited by the boorish and overly pampered bourgeoisie".

The film was one of Berger's biggest productions according to its budget and boasted a distinguished cast, including Alfred Abel and Max Schreck. Russian-born actor Nikolai Malikoff received glowing reviews for his portrayal of Rasputin, although his film career petered out soon after due to the advent of sound. (This film is sometimes confused with a 1928 German-Russian film called Rasputin (1928 film).)
