Jonny Quest (also known as The Adventures of Jonny Quest) is an American animated science fiction adventure television series about a boy who accompanies his scientist father on extraordinary adventures. It was produced by Hanna-Barbera Productions for Screen Gems, and created and designed by comic book artist Doug Wildey.

Inspired by radio serials and comics in the action-adventure genre, it featured more realistic art, characters, and stories than Hanna-Barbera's previous cartoon programs. It was the first of several Hanna-Barbera action-based adventure shows – which would later include Space Ghost, The Herculoids, and Birdman and the Galaxy Trio – and ran on ABC in prime time on early Friday nights for one season in 1964–1965.

After spending two decades in reruns, during which time it appeared on all 3 major US television networks of the time, new episodes were produced for syndication in 1986 as part of The Funtastic World of Hanna-Barbera's second season. Two telefilms, a comic book series, and a more modern revival series, The Real Adventures of Jonny Quest, were produced in the 1990s.

Comic book artist Doug Wildey, after having worked on Cambria Productions' 1962 animated television series Space Angel, found work at the Hanna-Barbera studio, which asked him to design a series starring the radio drama adventure character Jack Armstrong, the All-American Boy.
