The Secret Saturdays is an American animated television series created by Canadian cartoonist Jay Stephens for Cartoon Network. It debuted on October 3, 2008, in the United States. The series follows the adventures of the Saturdays, a family of cryptozoologists that work to keep the truth about cryptids from getting out, to protect both the human race and the creatures themselves. The Saturdays travel the Earth searching for cryptids to study and battling twisted villains like the megalomaniac V. V. Argost. The series is influenced by 1960s-era Hanna-Barbera action series and is combined with Jay Stephens's own personal interest in cryptozoology. The show finished its run on January 30, 2010, but continued to air reruns on Boomerang until June 2, 2014.

The Secret Saturdays was the first Cartoon Network original series to be broadcast in high-definition.
