Adventures of Huckleberry Finn, also called The Adventures of Huckleberry Finn, novel by Mark Twain, published in the United Kingdom in 1884 and in the United States in 1885. The book's narrator is Huckleberry Finn, a youngster whose artless vernacular speech is admirably adapted to detailed and poetic descriptions of scenes, vivid representations of characters, and narrative renditions that are both broadly comic and subtly ironic. Huck runs away from his abusive father and, with his companion, the runaway slave Jim, makes a long and frequently interrupted voyage down the Mississippi River on a raft. During the journey Huck encounters a variety of characters and types in whom the book memorably portrays almost every class living on or along the river. As a result of these experiences, Huck overcomes conventional racial prejudices and learns to respect and love Jim. The book's pages are dotted with idyllic descriptions of the great river and the surrounding forests, and Huck's good nature and unconscious humour permeate the whole. But a thread that runs through adventure after adventure is that of human cruelty, which shows itself both in the acts of individuals and in their unthinking acceptance of such institutions as slavery. The natural goodness of Huck is continually contrasted with the effects of a corrupt society.
