Transformers: Robots in Disguise is an American science-fiction animated television series for children produced by Hasbro Studios and Darby Pop Productions in the United States for Cartoon Network. It was also animated by Polygon Pictures in Japan. It is the stand-alone sequel to Transformers: Prime that ran from 2010 to 2013 on The Hub Network, featuring characters (most of whose voice actors reprise their roles) and storylines mostly self-contained from the events of its predecessor as well as an overall more lighthearted tone. Roberto Orci and Alex Kurtzman (the executive producers of Prime) did not return to the new series. In the United States, the series ran on Cartoon Network from March 14, 2015, to November 11, 2017.

The show's second season, featuring guest appearances from some returning Transformers: Prime characters, premiered on February 20, 2016. A six-episode mini-series centered on the return of Starscream premiered in Canada on September 10, 2016, before debuting on U.S. television the following month. The third and final season, subtitled Combiner Force, aired from April 29, 2017, to November 11, 2017.

It was the first Transformers series to feature Bumblebee as the main protagonist rather than Optimus Prime, the leader of the Autobots and the main protagonist in most of the other series (though Optimus appears in a semi-regular role throughout Robots in Disguise).

Three years after Megatron's exile, the Predacons' defeat, and life being restored to the planet Cybertron, a new generation of Transformers enjoy a new age of prosperity. Earth no longer remembers the Decepticon-Autobot conflict as the Cybertronians stopped visiting the planet. Bumblebee has since become a seasoned Cybertronian police officer and despite his fame, he chooses to be a humble peacekeeper. Things change when he is summoned by the vision of Optimus Prime. Thought to be long dead after restoring Cybertron's population, Optimus Prime calls for Bumblebee to return to Earth as a new threat appears.
