Tom Swift is the main character of six series of American juvenile science fiction and adventure novels that emphasize science, invention, and technology. Inaugurated in 1910, the sequence of series comprises more than 100 volumes. The first Tom Swift – later, Tom Swift Sr. – was created by Edward Stratemeyer, the founder of the Stratemeyer Syndicate, a book packaging firm. Tom's adventures have been written by various ghostwriters, beginning with Howard Garis. Most of the books are credited to the collective pseudonym "Victor Appleton". The 33 volumes of the second series use the pseudonym Victor Appleton II for the author. For this series, and some later ones, the main character is "Tom Swift Jr." New titles have been published again from 2019 after a gap of about ten years, roughly the time that has passed before every resumption. Most of the series emphasized Tom's inventions. The books generally describe the effects of science and technology as wholly beneficial, and the role of the inventor in society as admirable and heroic.

Edward L. Stratemeyer was an American publisher, writer of children's fiction, and founder of the Stratemeyer Syndicate. He was one of the most prolific writers in the world, producing in excess of 1,300 books himself, selling in excess of 500 million copies. He also created many well-known fictional book series for juveniles, including The Rover Boys, The Bobbsey Twins, Tom Swift, The Hardy Boys, and Nancy Drew series, many of which sold millions of copies and remain in publication. On Stratemeyer's legacy, Fortune wrote: "As oil had its Rockefeller, literature had its Stratemeyer."
