Reginald Lucien Frank Roger Watts (born March 23, 1972) is an American comedian, actor, beatboxer, and musician. His improvised musical sets are created using only his voice, a keyboard, and a looping machine. Watts refers to himself as a "disinformationist" who aims to disorient his audience in a comedic fashion. He was the regular house musician on the spoof IFC talkshow Comedy Bang! Bang! and leads the house band for The Late Late Show with James Corden.

Watts utilizes improvisation in his solo shows, which consist of him singing and rapping both with words and with sound poetry, accompanying himself by either beatboxing, performing vocal basslines into a loop machine, or simply by playing the keyboard. His act also showcases his trademark style of stand-up comedy, consisting of him rapidly alternating between topics of discussion in both rational and nonsensical manners, making random sounds and gibberish noises, and speaking in other accents and languages at unexpected times, all with the intent of playfully and comically disorienting his audiences. He has a four-and-a-half octave vocal range.
