Kim Rock Hyun, known mononymously as Rockhyun, is a South Korean singer, dancer, former member of JUMPER (점퍼) and 100% (백퍼센트) and current member of FAVE1 (페이브원). He graduated from Gwangmyeong Information Industry High School.

Before debuting, he was a trainee at TOP Media (티오피미디어), and SHINHWA's Andy became their main producer. He was placed in the duo JUMPER, alongside Park Dong Min, and made his debut in mid-2009 with the singles "Yes!" and "Dazzling". This served as a trial to evaluate if both members were ready to perform as idols.

He re-debuted in September 2012 as 100%'s main vocalist with their first single album, "We, 100%". The group had some commercial success thanks to the agency's strategy of pairing them with label mate group TEEN TOP.

In November 2013, he became part of the sub-unit 100% V (백퍼센트 V) and released their first self-titled single album.

He enlisted for his mandatory military service on July 15, 2019, and was discharged on February 7, 2021.

In October 2021, TOP Media announced the group's disbandment following the expiration of their contracts.

He then stayed out of the industry for some time and moved to Japan. He re-debuted in July 2022 as FAVE1's main vocalist with their first single, "Zombie". The group is managed by Kiss Entertainment (キッス・エンタテインメント).
