In Search of the Castaways (, lit. The Children of Captain Grant) is a novel by the French writer Jules Verne, published in 1867–1868. The original edition, published by Hetzel, contains a number of illustrations by Édouard Riou. In 1876, it was republished by George Routledge & Sons as a three volume set titled A Voyage Round The World. The three volumes were subtitled South America, Australia, and New Zealand. As often with Verne, English translations have appeared under different names; another edition has the overall title Captain Grant's Children and has two volumes subtitled The Mysterious Document and Among the Cannibals.
