Jeong Jae Hyun, later legally changed to Jeong Yun Oh and known professionally as Jaehyun, is a South Korean singer, dancer, actor, and member of NCT (엔시티) and 3 of its sub-units, NCT U (엔씨티 유), NCT 127 (엔씨티 127), and NCT DOJAEJUNG (NCT 도재정). He graduated from Seoul Performing Arts High School.

He joined SM Entertainment (SM엔터테인먼트) in 2012 after being scouted on the street in front of his school. In December 2013, he was introduced as a member of the pre-debut trainee team SM ROOKIES. Then, SM decided to create a 25-member group that was divided into separate sub-units. They quickly became known as South Korea's "most experimental band" due to their concept of having members switch units freely.

He made his debut in April 2016 as part of the rotational sub-unit NCT U with their double digital singles "The 7th Sense" and "Without You". Then, in July of that year, he debuted as NCT 127's main vocalist, lead dancer, sub-rapper and visual with their EP also titled "NCT 127".

He made his acting debut as the male lead in the drama “Dear M” in 2022 and is also an ambassador of Italian brand Prada and Korean brand Clio Cosmetics.

He also made his debut in April 2023 as part of the trio sub-unit NCT DOJAEJUNG with their EP, "Perfume".

He enlisted for his mandatory military service on November 4, 2024, and was discharged on May 3, 2026.
