Dangerous Hours is a 1919 American silent drama film directed by Fred Niblo. Prints of the film survive in the UCLA Film and Television Archive. It premiered in February 1920.

The film was based on a short story "A Prodigal in Utopia" published in the Saturday Evening Post. The film's working title was Americanism (Versus Bolshevism), which was the title of a pamphlet published by Ole Hanson, the mayor of Seattle who claimed to have broken the Seattle General Strike in 1919.
