Treasure Island is a 1920 silent film adaptation of the 1883 novel by Robert Louis Stevenson, directed by Maurice Tourneur, and released by Paramount Pictures. Lon Chaney played two different pirate roles in this production, "Blind Pew" and "Merry", and stills exist showing him in both makeups. Charles Ogle, who had played Frankenstein's Monster in the first filmed version of Frankenstein a decade earlier at Edison Studios, portrayed Long John Silver. (Jack Holt was originally supposed to play that part.) Wallace Beery was supposed to play Israel Hands, but that role went to Joseph Singleton instead. The film was chosen as one of the Top Forty Pictures of the Year by the National Board of Review.

The film is now considered a lost film. Reproductions of the film's posters still exist.
