Lee Ji Hoon, known professionally as Woozi, is a South Korean singer, songwriter, producer and member of SEVENTEEN (세븐틴). He graduated from Hanlim Multi-Arts High School and is currently enrolled in the K-pop program at Hanyang University, as well as the Master's degree program in Integrated Business Administration at Anyang University.

He became a trainee under Pledis Entertainment (플레디스 엔터테인먼트) in 2011, and he was one of the original Pledis Boys. The agency had two potential new groups, NU’EST (뉴이스트) and TEMPEST (템페스트; not to be confused with the group under Yuehua Entertainment that debuted in 2022). He was assigned to TEMPEST, but the project was cancelled as NU'EST found immediate success, and the public paid no attention to the other group.

He made his debut in May 2015 as SEVENTEEN's vocal team leader, lead vocalist, and producer with their first mini-album, "17 Carat". He is part of the sub-units SVT LEADERS alongside S.Coups and Hoshi, and VOCAL TEAM alongside Jeonghan, Joshua, DK, and Seungkwan. They debuted in May 2015, releasing record tracks as unit songs for group albums and mixtapes.

He has written and produced numerous songs for his own group, as well as for others. In January 2019, Woozi was promoted to a full member of the Korean Music Copyright Association (KOMCA).

In March 2025, he debuted as part of the duo HOSHI x WOOZI (호시 x 우지), with their first album, "BEAM".

He enlisted for his mandatory military service on September 15, 2025 and was discharged on March 14, 2027.
