What river is featured in Mark Twain's 'The Adventures of Tom Sawyer'?

The Mississippi River is the river featured in Mark Twain's The Adventures of Tom Sawyer.

Published in 1876, the novel is set in the fictional town of St. Petersburg, Missouri, beside the Mississippi. The setting draws heavily on Twain's childhood in Hannibal, Missouri, and the river becomes part of the book's landscape, adventures, and sense of freedom.

Tom Sawyer and Huckleberry Finn treat the river as a place of escape. They run away to Jackson's Island, where they imagine themselves as pirates, while the townspeople search the river after assuming the boys have drowned. Rafts, caves, and river travel also connect the story to the broader culture of the American Mississippi Valley.

The Missouri and Ohio rivers are plausible distractors because both are major waterways in the region, but the novel's defining river is the Mississippi. Twain later returned to the same river world in Adventures of Huckleberry Finn.
