Johanna Enlists is a 1918 silent film comedy drama produced by and starring Mary Pickford with distribution by Paramount Pictures. The film was directed by William Desmond Taylor from a short story by Rupert Hughes, The Mobilization of Johanna. Frances Marion, a frequent Pickford collaborator, wrote the scenario. The film was made at a time during World War I when sentimental or patriotic films were immensely popular. It was an early starring vehicle for Monte Blue, the male lead opposite Pickford. The film survives in several prints, including one at the Library of Congress.
