Maria Marten, or the Mystery of the Red Barn

Maria Marten, or the Mystery of the Red Barn is a 1913 British silent drama film directed by Maurice Elvey. It was based on the 1827 Red Barn Murder. A Suffolk squire murders a young pregnant woman who had demanded that he marry her. The story of Maria Marten was a popular stage melodrama of the Victorian era, and five films based on the story were made between 1902 and 1935.

As of August 2010, the film is missing from the BFI National Archive, and is listed as one of the British Film Institute's "75 Most Wanted" lost films.
