Cartoon Cartoons is a collective name used by Cartoon Network for their original animated television series originally aired between 1995 and 2003 and produced in majority by Hanna-Barbera and/or Cartoon Network Studios. Beginning with its inception into cable broadcasting on October 1, 1992, Cartoon Network had focused its programming on reruns of older animated series which it had acquired through its parent company's film library. The Cartoon Cartoons label originated with Fred Seibert's animation anthology series What a Cartoon!, an animation showcase series featuring pilots of original cartoon ideas submitted by independent animators. Dexter's Laboratory was the first such pilot to be greenlit by the network for a full series in 1996. After other pilots were successfully produced into their own series, including Cow and Chicken, Johnny Bravo, and The Powerpuff Girls, the collective Cartoon Cartoons were featured on the network's Friday night programming block, Cartoon Cartoon Fridays from 1999 to 2003. Not all CN original series created around this time were officially recognized as Cartoon Cartoons; Samurai Jack, for example, did not bear the moniker.

The moniker was retired by the network in 2004, and its last surviving series, Ed, Edd n Eddy, ended in 2009 after a ten-year run. Since their heyday, reruns of the Cartoon Cartoons continued to air on The Cartoon Cartoon Show (2005–2008) and Cartoon Planet (2012–2014). In 2021, the name was resurrected by the network for a new shorts program.
