Upstream is a 1927 American comedy film directed by John Ford. A "backstage drama", the film is about a Shakespearean actor and a woman from a knife-throwing act. The film was considered to be a lost film, but in 2009 a print was discovered in the New Zealand Film Archive.

It is considered to be the first Ford film to show some influence of German director F. W. Murnau, who began working at Fox Studios in 1926. From Murnau, Ford learned how to use forced perspectives and chiaroscuro lighting, which the American director then integrated into his own more naturalistic and direct filmmaking style.
