Stuart Webbs is a fictional detective who appeared in a series of German films and serials during the silent era. Webbs was one of a number of detectives with English-sounding names to appear in German cinema of the era. Like his contemporaries, such as Joe Deebs, he was modelled on Sherlock Holmes. Webbs was the most popular of the group. His original film series ran from 1914 to 1926, and he continued to appear in other later films such as The Green Monocle (1929).
Webbs was played by Ernst Reicher until 1926. A number of figures directed entries in the series including Joe May, Johannes Guter and Robert Wiene. The series was originally made by Continental-Kunstfilm, but following a dispute May and Reicher left to form their own production company, Stuart Webbs-Film.
The role of Stuart Webbs was played by Ernst Reicher, and once each by Fritz Greiner, Ralph Clancy, and Karl Ludwig Diehl. Joe May directed the films, but directors Adolf Gärtner, Johannes Guter, Max Obal, Robert Wiene, Franz Seitz Sr., Lupu Pick, Rudolf Meinert, and Ernst Reicher himself also contributed. The directors of some films are unknown.
Stuart Webbs was a gentleman detective modelled after Sherlock Holmes, who solved even the most difficult cases with intelligence and elegance. Throughout the First World War, this fictional character was popular with German cinema audiences.

Two late additions to the series were the silent films The Green Monocle () with Ralph Clancy and Masks () with Karl Ludwig Diehl, both in 1929.
