Mixels is an American animated television series that aired on Cartoon Network and was produced by Cartoon Network Studios. Following colorful creatures known as Mixels, the series depicts their exploits involving their ability to combine with one another in order to solve problems or fight against their enemy: the Nixels. The series first aired on February 12, 2014, with a new episode of Teen Titans Go!, and the series ran for two seasons, concluding on October 1, 2016.

Although previous Lego series, such as Lego Ninjago and Lego Legends of Chima, use CGI animation, Mixels made use of Toon Boom Harmony software, animated at Atomic Cartoons, Inc., before later being animated traditionally at Digital eMation, Inc., Big Star Entertainment, Inc., and Saerom Animation, Inc. A mobile app was released for the series on March 4, 2014, named Calling All Mixels, and even earlier two websites, one on the LEGO website and another owned by Cartoon Network, were launched where fans can learn about the Mixels. Nine series of collectible Lego building toys were also released, based on the characters. On February 19, 2014, the series had begun airing as an interstitial program on Boomerang.

The TV series wrapped up production in July 2016, and the series finale aired on October 1, 2016.
