The Moonstone is a 1934 American mystery film directed by Reginald Barker and starring David Manners, Phyllis Barry, Gustav von Seyffertitz and Jameson Thomas. It is an adaptation of the 1868 novel The Moonstone by Wilkie Collins. The film retains the book's British location, but uses a contemporary 1930s setting rather than the Victorian era of the original. It is one of three film versions of the novel, which include silent versions in 1915 and 1909, although a number of television and radio adaptations have been made.
