Lee Dong Hyuk, known professionally as Haechan, is a South Korean singer, dancer, and member of NCT (엔시티) and 3 of its sub-units, NCT U (엔씨티 유), NCT 127 (엔씨티 127), and NCT DREAM (엔씨티 DREAM). He dropped out of high school but later passed the High School Graduation Certification Examination.

He joined SM Entertainment (SM엔터테인먼트) in 2013 after passing the SM Saturday Open Auditions. He was then introduced as part of SM ROOKIES in July 2014. The company 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 July 2016 as NCT 127's main vocalist, lead dancer and maknae with their EP also titled "NCT 127". The following month, he debuted as NCT DREAM's main vocalist with their digital single "Chewing Gum".

In December 2019, he joined the rotational sub-unit NCT U with the release of the single "Coming Home" under the SM Station project.

In 2024, after the debut of their sixth unit, NCT WISH, SM Entertainment decided to stop adding more members or creating sub-units.
