Cartoon Planet is an animated variety show that originally premiered in 1995 on TBS Superstation and continued its run from 1996 to 1997 on Cartoon Network. A spin-off of the animated Space Ghost Coast to Coast talk show, the premise was that Space Ghost had recruited his imprisoned evil arch nemesis Zorak and his loud and extremely dimwitted archenemy Brak to assist him in hosting a variety show.

Cartoon Planet began as an hour-long block of cartoons hosted by Space Ghost, Zorak, and Brak. They would introduce full cartoons from the Turner Entertainment library, such as old theatrical shorts and Hanna-Barbera cartoons, including the original 1960s Space Ghost episodes. The host segments were often original songs and ad libbed skits. New material ceased being made in 1997, and most of the songs and skits were re-packaged into 22 half-hour episodes without cartoons.

On March 30, 2012, Cartoon Network relaunched Cartoon Planet in the form of a Friday night classic cartoon block hosted by Brak and Zorak to celebrate the network's 20th anniversary.
