The Sin of Olga Brandt is a 1915 American silent drama film directed by Joe De Grasse and featuring Lon Chaney and Pauline Bush. Jon Mirsalis claims the film was written by Ida May Park (De Grasse's wife) and that "some sources suggest that the film, which preaches about the high morality of moving pictures, was instigated by (producer) Carl Laemmle, who was involved in censorship fights of his own over some of his releases". The film is now considered to be lost. A still exists showing Lon Chaney as Stephen Leslie, trying to intimidate Olga Brandt (see plot). Plot Olga is a stenographer working in the office of an attorney, Stephen Leslie (Lon Chaney). She cares for her invalid sister who needs an expensive operation to save her life, so she appeals to her employer who agrees to give her the money only if she will give herself to him sexually. Having no choice, she reluctantly agrees to move in with him; however, three months later, her sister dies and she realizes her sacrifice was all for naught.

Deacon Jellice wants the picture banned and a lawyer is called in to arbitrate. The lawyer turns out to be Stephen Leslie, who sees Olga and threatens to expose her past transgressions if she does not move back into his home and be his mistress once again. Olga plans to run away from both men this time and leaves a written confession for Reverend John to find, but on her way out of town, she chances to enter the theatre where the film is playing.

Catching Olga at the train station, he asks her forgiveness and tells her that she should go home to her husband. She returns home where the Reverend John has already read her confession, but remembering the moral of the picture,
