S.O.S. Eisberg (aka S.O.S. Iceberg and Iceland) is a 1933 German-US pre-Code drama film directed by Arnold Fanck and starring Gustav Diessl, Leni Riefenstahl, Sepp Rist, Gibson Gowland, Rod La Rocque, and Ernst Udet. The film was written by Tom Reed based on a story by Arnold Fanck and Friedrich Wolf. S.O.S. Eisberg follows the account of the real-life Alfred Lothar Wegener polar expedition of 1929-30. Two members of the ill-fated Wegener expedition served as technical consultants to Universal.

Among the stars in S.O.S. Eisberg were Leni Riefenstahl, who had just made her directorial debut in The Blue Light (1932). Riefenstahl, in her last film as an actress, co-starred with Gustav Diessl and Ernst Udet in the German version S.O.S. Eisberg, and with Gibson Gowland and Rod La Rocque in the English version, S.O.S. Iceberg. Ernst Udet, a former German ace in the First World War, in a cameo performance, flew in both versions.
