The President Vanishes (released in the United Kingdom as Strange Conspiracy) is a 1934 American political drama film directed by William A. Wellman and produced by Walter Wanger. Starring Edward Arnold and Arthur Byron, the film is an adaptation of Rex Stout's political novel of the same name.

Upon its release, the film was praised for its ensemble cast but author John Douglas Eames, in his 1985 book The Paramount Story, stated that, even with "an accomplished cast and an out-of-the-rut story, The President Vanishes couldn't buck moviegoers' apathy towards political subjects".
