The Man Who Was Sherlock Holmes (German: Der Mann, der Sherlock Holmes war) is a 1937 German mystery comedy film directed by Karl Hartl and starring Hans Albers, Heinz Rühmann and Marieluise Claudius.

The film's sets were designed by the art director Otto Hunte and Willy Schiller.

Detective Morris Flynn (Hans Albers) and his assistant Macky McMacpherson (Heinz Rühmann), masquerading as Sherlock Holmes and Dr Watson, investigate two attractive sisters, Mary and Jane Berry, and the theft and forgery of valuable postage stamps.

Lexikon des Internationalen Films calls it a swinging, lively comedy.

Albers and Rühmann were two longtime major stars of German cinema and are still known for the main song in this movie, Jawoll, meine Herr'n.
