The New Adventures of Huckleberry Finn is an American live-action and animated fantasy television series that originally aired on NBC from September 15, 1968, through February 23, 1969. Produced by Hanna-Barbera and based on the classic Mark Twain characters, the program starred its three live-action heroes, Huck Finn, Becky Thatcher, and Tom Sawyer, navigating weekly adventures within an animated world as they attempted to outrun a vengeful "Injun Joe".
