Lee Dong Hun is a South Korean singer, dancer and member of A.C.E (에이스). He graduated from Changhyun High School and later obtained a bachelor's degree in Applied Music from Pyeongtaek University.

He first appeared on TV as a contestant in "Superstar K5", where he reached the Top 10. In early 2017, he participated in the survival show "MIXNINE", making it into the final lineup after finishing in 8th place. However, YG Entertainment decided to cancel the resulting project group claiming the show was not successful, so debuting a group presented a huge risk for the company.

After switching agencies, he made his debut in May 2017 as A.C.E's main vocalist with their first single album, "Cactus". The group enjoyed initial success thanks to the agency's idea of going busking in Hongdae while covering well-known songs.

He enlisted for his mandatory military service on September 23, 2021, and was discharged on June 22, 2023.

In July 2024, Beat Interactive (비트 인터렉티브) announced he would join IMFACT's Park Je Up to form duo D&J (이동훈&박제업). Some days later, they released their first digital single, "I Still".
