"St. Ives" (AKA St. Ives: The Adventures of a French Prisoner in England) is an unfinished novel created by Scottish author Robert Louis Stevenson in 1897 that was completed in 1898 by Arthur Quiller-Couch. Unable to write, Stevenson dictated thirty chapters of the novel to his stepdaughter, Mrs. Strong, as a diversion from his debilitating illness. Written while Stevenson lived in Samoa, "St. Ives" was the author's last title.

Set during the Napoleonic Wars, "St. Ives" narrates the adventures of the dashing Viscomte Anne de Keroual de St. Ives, a Napoleonic soldier enlisted as a private under the name of Champdivers, after his capture by the British and during his stay as a prisoner in Edinburgh Castle.
