Cartoon Network (often abbreviated as CN) is an American cable television channel owned by Warner Bros. Discovery. It is the flagship property of The Cartoon Network, Inc., a division that also oversees Boomerang, Cartoonito, Discovery Family, Adult Swim, and Toonami. The channel is headquartered at 1050 Techwood Drive NW in Atlanta, Georgia.

Founded by Betty Cohen (who was also appointed by Ted Turner as the first president of the network), the channel was launched on October 1, 1992, and primarily broadcasts animated television series, mostly children's programming, ranging from action to animated comedy. It currently runs from 6 a.m. to 5 p.m. ET/PT daily, though the sign-off time varies with holidays and special programming. Cartoon Network primarily targets children aged 6 to 12, while its early morning block Cartoonito is aimed at preschool-aged children, and evening block Adult Swim targets young adults aged 18 to 34.

As of November 2023, Cartoon Network is available to approximately 66 million pay television households in the United States—down from its peak of 100 million households in 2011.
