Katsuhiko Nakajima (中嶋 勝彦, Nakajima Katsuhiko, born March 11, 1988) is a Japanese professional wrestler currently working as a freelancer.

He is best known for his work in Pro Wrestling Noah, where he was a former two-time GHC Heavyweight Champion, six-time GHC Tag Team Champion, one-time GHC National Champion, and three-time GHC Junior Heavyweight Champion. He started his career in Kensuke Sasaki's Kensuke Office (later renamed to Diamond Ring) dojo and agency. In AJPW, he is a former World Junior Heavyweight Champion. A former amateur karateka, his style is based upon strong, fast kicks and strikes; his style has been dubbed by Nakajima as "Toukon Style" (闘魂 STYLE, Tōkon sutairu), before reaniming it to "XX Style" following a trademark dispute by IGF.

Having made his professional debut aged 15 in a mixed martial arts contest, Nakajima has already made a significant impact on puroresu, earning the nickname "Supernova" and facing Hall of Famers such as Kenta Kobashi, Satoru Sayama, Jushin Thunder Liger, and Tatsumi Fujinami. He has competed in several notable Japanese promotions, including New Japan Pro Wrestling, All Japan Pro Wrestling, Inoki Genome Federation, Pro Wrestling Zero1, Michinoku Pro, Dragon Gate, and Pro Wrestling Noah.

He has set several age records over his short career, including being the youngest wrestler to compete in AJPW's Champion Carnival tournament and the youngest to hold the World Junior Heavyweight Championship. He won the Tokyo Sports "Rookie of the Year" award in 2004 and the Fighting Spirit award in 2005. Having worked for Noah for most of his career, both as a representative of Diamond Ring and as a freelancer, he officially signed with the promotion in December 2015. He left in October 2023 and, later, found himself as AJPW's Triple Crown Heavyweight Champion after defeating Yuma Aoyagi the next month. He held the title for five months, before leaving AJPW in March 2024.
