Invisible Opponent (German: Unsichtbare Gegner) is a 1933 German-Austrian drama film directed by Rudolph Cartier and starring Gerda Maurus, Paul Hartmann, and Oskar Homolka. The film's sets were designed by the art director Erwin Scharf. The film was made at the Sievering Studios in Vienna. The critics were not generally impressed with the film, with the Deutsche Allgemeine Zeitung describing it as an "unbelievable and unbelievably awful picture".
A separate French-language version The Oil Sharks was also released.
