Kim Jung Woo, previously known professionally as Yoosung, is a South Korean singer, dancer, model and former member of COED SCHOOL (남녀공학) and SPEED (스피드). He attended the Advertising Design program at Bucheon University but dropped out.

He made his debut in September 2010 (under the stage name Yoosung) as COED SCHOOL's leader and main vocalist with their first digital single, "Too Late". However, MBK Entertainment (MBK엔터테인먼트, formerly known as Core Contents Media) opted to create two separate groups, one for the boys and another for the girls. He re-debuted in January 2013 (now using his real name) as SPEED's main vocalist and second visual with their digital single "Speed of Light".

In November 2015, MBK announced the group's disbandment. His contract ended in January 2016, and he left the company.

He tried to become an actor in South Korea but decided to leave the country in early 2023. He is currently active as an influencer, advertising model and DJ in China.
