Yankee Doodle in Berlin is a 1919 American silent comedy and World War I film from producer Mack Sennett. A five-reel feature, it was Sennett's most expensive production up to that time. Hiram Abrams was the original State's Rights marketer before the film's release, but producer Sol Lesser bought the rights in March 1919.

Bothwell Browne was a famous cross-dresser from Northern Europe. At the time this movie was produced he was the European rival of famous American cross-dresser Julian Eltinge, who starred in very similar plotted World War I propaganda film The Isle of Love (original title Over the Rhine).

The film was later condensed for rerelease and titled The Kaiser's Last Squeal.

The film is preserved by the Library of Congress. Copies also held by Museum of Modern Art, BFI Film and Television, Cinematheque Royale de Belgique, Academy Film Archive Bev. Hills.
