The Adventures of Tom Sawyer (Japanese: トム・ソーヤーの冒険, Hepburn: Tomu Sōyā no Bōken) is a Japanese anime television series produced by Nippon Animation and directed by Hiroshi Saito, which premiered on January 6, 1980, and ended its run on December 28 the same year. It is based on the 1876 novel The Adventures of Tom Sawyer by Mark Twain (and partially on The Adventures of Huckleberry Finn).

The series was broadcast on the World Masterpiece Theater, an animation staple on Fuji TV, that each year showcased an animated version of a classical book or story of Western literature, and was originally titled Tom Sawyer no Bōken. It was the second installment of the series, after Rascal the Raccoon in 1977, to feature the work of an American author.

This series was dubbed into English by Saban International and broadcast on HBO in 1988 under the title The Adventures of Tom Sawyer at 7:30 am. It alternated with the later World Masterpiece Theater version of Little Women. Celebrity Home Entertainment released videos in the United States under the title All New Adventures of Tom Sawyer. It has also been dubbed in other languages, including French, Italian, Arabic, Hebrew, Portuguese, German, Hungarian, Dutch and Spanish. In January 2011, it was shown in the United States in the original Japanese on the NHK's cable channel TV Japan.
