The Mysterious Island () is a novel by Jules Verne, published in 1875. The original edition, published by Hetzel, contains a number of illustrations by Jules Férat. The novel is a crossover sequel to Verne's famous Twenty Thousand Leagues Under the Seas (1870) and In Search of the Castaways (1867–68), though its themes are vastly different from those books. An early draft of the novel, initially rejected by Verne's publisher and wholly reconceived before publication, was titled Shipwrecked Family: Marooned with Uncle Robinson, seen as indicating the influence of the novels Robinson Crusoe and The Swiss Family Robinson. Verne developed a similar theme in his later novel, Godfrey Morgan (French: L'École des Robinsons, 1882). The chronology of The Mysterious Island is incompatible with that of the original Twenty Thousand Leagues Under the Sea, whose plot begins in 1866, while The Mysterious Island begins during the American Civil War, yet is supposed to happen some years after Twenty Thousand Leagues. Plot summary During the American Civil War, five Northern prisoners of war escape during the Siege of Richmond, Virginia, by hijacking a hydrogen-filled observation balloon.

The company is completed by Cyrus's dog "Top". After flying in a great storm for several days, the group crash-lands on a cliff-bound, volcanic, unknown island, described as being located at (Southern Pacific Ocean/Asian:Oceanian side), about east of New Zealand. They name it "Lincoln Island" in honor of Abraham Lincoln. With the knowledge of the brilliant engineer Smith, the five are able to sustain themselves on the island, producing fire, pottery, bricks, nitroglycerin, iron, an electric telegraph, a cave home inside a stony cliff called "Granite House", and even a seaworthy ship, which they name the "Bonadventure". During their stay on the island, the group endures bad weather and domesticates an orangutan, Jupiter, abbreviated to Jup (or Joop, in Jordan Stump's translation). There is a mystery on the island in the form of an unseen deus ex machina, responsible for Cyrus' survival after falling from the balloon, the mysterious
