"Adventures of Huckleberry Finn" (often shortened to "Huck Finn") is a novel written by Mark Twain and published in 1884. It is commonly regarded as one of the "Great American Novels" and is one of the first major American novels written in the vernacular, characterized by local color regionalism.

It is told in the first person by Huckleberry "Huck" Finn, best friend of Tom Sawyer and narrator of two other Twain novels.
