Jung Jin Woon is a South Korean singer, actor, and member of 2AM (투에이엠). He graduated from Baekam High School and later obtained a bachelor's degree in Theater and Film from Daejin University.

In early 2008, JYP Entertainment (JYP엔터테인먼트) launched a reality/documentary show called "Hot Blood Men" capturing the training program of 14 trainees. He was one of 3 trainees who were eliminated in the final round. However, he was brought back after another trainee decided to withdraw from the show and the agency. The 11 trainees joined to create ONE DAY (원데이), and almost immediately, they were split into two separate groups, ballad-oriented 2AM (4 trainees) and hip-hop/R&B-oriented 2PM (7 trainees).

He made his debut in July 2008 as 2AM's vocalist, main rapper and maknae with the single "This Song". The group found commercial success from the beginning, with most of their singles charting inside the top-ten in all major South Korean charts.

He made his debut as a solo artist in August 2011 with the single "You Walking Towards Me”, which he composed.

As some members left JYP, the group went on a 7-year hiatus with 3 members fulfilling their mandatory military service and, later, being involved in other individual activities. He left the agency in early 2015 and signed with Mystic Story (미스틱스토리). He enlisted for his mandatory military service on March 4, 2019, and was discharged on October 7, 2020.

The group reunited in 2021 and released their fourth EP, "Ballad 21 F/W", and now continue to actively promote and also handle their individual activities.
