Yoon Kye-sang
Yoon Kye-sang (윤계상, born December 20, 1978) is a South Korean actor and former idol who parlayed a career in first-generation K-pop into one of the most respected acting careers of his generation. He debuted in 1999 as a vocalist of g.o.d (지오디) after auditioning on a whim at his father's suggestion, quickly becoming part of the group's defining lineup.
He left g.o.d in 2004 to pursue acting full-time. His film debut in Flying Boys (2004) immediately signaled his dramatic range, earning him Best New Actor at the Baeksang Arts Awards. He spent the next decade building an impressive resume across genres: melodrama (On Air, 2008), crime (The Chaser, 2008), medical (Good Doctor, 2013), legal thriller (Pride and Prejudice, 2014), and action (The Outlaws series, 2017-2022).
The Outlaws franchise proved a career-defining turn: as the villainous Jang Chen across three films, Yoon Kye-sang delivered a performance that became one of the most discussed antagonist portrayals in Korean cinema of the 2010s.
He rejoined g.o.d for the group's 2014 reunion and has remained an active member at concerts. In 2025, he led the SBS sports drama The Winning Try (July-August 2025) as passionate rugby coach Joo Ga-ram, winning the Director's Award at the 2025 SBS Drama Awards. He is represented by Cracker Entertainment.
