Huckleberry "Huck" Finn is a fictional character created by Mark Twain who first appeared in the book The Adventures of Tom Sawyer (1876) and is the protagonist and narrator of its sequel, Adventures of Huckleberry Finn (1884). He is 12 to 13 years old during the former and a year older at the time of the latter. Huck also narrates Tom Sawyer Abroad and Tom Sawyer, Detective, two shorter sequels to the first two books.

The Adventures of Tom Sawyer is an 1876 novel by Mark Twain about a boy, Tom Sawyer, growing up along the Mississippi River. It is set in the 1840s in the town of St. Petersburg, which is based on Hannibal, Missouri, where Twain lived as a boy. In the novel, Sawyer has several adventures, often with his friend Huckleberry Finn. Originally a commercial failure, the book ended up being the best-selling of Twain's works during his lifetime. Though overshadowed by its 1884 sequel, Adventures of Huckleberry Finn, the book is considered by many to be a masterpiece of American literature. It is alleged by Mark Twain to be one of the first novels to be written on a typewriter.
