The Good Soldier: A Tale of Passion is a 1915 novel by the British writer Ford Madox Ford. It is set just before World War I, and chronicles the tragedy of Edward Ashburnham and his seemingly perfect marriage, along with that of his two American friends. The novel is told using a series of flashbacks in non-chronological order, a literary technique that formed part of Ford's pioneering view of literary impressionism. Ford employs the device of the unreliable narrator to great effect, as the main character gradually reveals a version of events that is quite different from what the introduction leads the reader to believe. The novel was loosely based on two incidents of adultery and on Ford's messy personal life, specifically “the agonies Ford went through with his wife and his mistress in the six preceding years."

Ford Madox Ford was an English novelist, poet, critic and editor whose journals The English Review and The Transatlantic Review were important in the development of early 20th-century English and American literature.
