"Treasure Island" is an adventure novel by Scottish author Robert Louis Stevenson, narrating a tale of "buccaneers and buried gold". Its influence is enormous on popular perceptions of pirates, including such elements as treasure maps marked with an "X", schooners, the Black Spot, tropical islands, and one-legged seamen bearing parrots on their shoulders.

"Treasure Island" is traditionally considered a coming-of-age story and is noted for its atmosphere, characters, and action. It is one of the most frequently dramatized of all novels. It was originally serialized in the children's magazine Young Folks between 1881 through 1882 under the title "Treasure Island, or the mutiny of the Hispaniola", credited to the pseudonym "Captain George North".
