Kim Joo Hyung, known mononymously as Joohyung, is a South Korean singer, dancer, and former member of NINE.i (나인아이). He graduated from Munjeong High School and, before debuting, spent one and a half years as a trainee.

He made his debut in March 2022 as the group's vocalist with their first mini album, "New World". He is also listed as a lyricist and composer for several of their songs.

However, in March 2024, all members (except Eden) became involved in a legal dispute with their agency, FirstOne Entertainment (퍼스트원 엔터테인먼트), for undisclosed reasons. In June of that year, the issue was resolved, but they went on hiatus to plan their future activities.

In December 2024, they made their debut in Japan with the single "Mirage". They will continue to promote there as they are currently without a South Korean agency to manage them.

On March 10, 2025, it was announced that Joo Hyung left NINE.i.
