Sym-Bionic Titan is an American animated television series created by Genndy Tartakovsky (in his fourth collaboration with the channel), Bryan Andrews and Paul Rudish for Cartoon Network. The series focuses on a trio consisting of the alien princess Ilana, the strict but rebellious alien soldier Lance, and the robot Octus, who arrive on Earth and combine themselves to create the titular Sym-Bionic Titan.

A preview of the series was first shown at the 2009 San Diego Comic-Con International, and further details were revealed at Cartoon Network's 2010 upfront. The series premiered on September 17, 2010, and ended on April 9, 2011, with a total of 20 episodes as ordered by the channel; Tartakovsky had hoped to expand on that, but the series was not renewed for a second season, as it "did not have any toys connected to it".While Sym-Bionic Titan has never been released to DVD in the United States, all 20 episodes were available for purchase on iTunes and the Microsoft Store. On October 7, 2012, reruns of the series began airing on Adult Swim's Toonami block along with the 2011 television series of ThunderCats until Cartoon Network wrote-off Sym-Bionic Titan for financial reasons in September 2014. The series was later released on Netflix in 2019, but was removed from the service in December 2020.
