Lee Joon-hyuk

Lee Joon-hyuk (이준혁) has built a career on playing morally complex characters with a precision that makes each one feel lived-in. Born in Seoul on March 13, 1984, he studied Advertising and Public Relations at Hanshin University before earning a graduate degree in Performing Arts at Dankook University. His breakout came with the role of prosecutor Seo Dong-jae in tvN's Stranger (2017-2020), a character whose slippery moral compass and layered performance won over critics and audiences across two seasons. Before that, he had already proven his range in City Hunter (2011) opposite Lee Min-ho, the family drama Three Brothers (2009), and Man from the Equator (2012). Lee's post-military career (2012-2014) saw him take increasingly diverse roles. He led the medical drama A Poem a Day (2018), played a political aide in Designated Survivor: 60 Days (2019), and anchored the time-travel mystery 365: Repeat the Year (2020), which earned him Best Acting at the Asia Artist Awards. His range extends to action with Dark Hole (2021) and the revenge thriller Vigilante (2023). In 2025, Lee starred in the SBS romance drama Love Scout opposite Han Ji-min, followed by a special appearance in Netflix's Mercy for None. He then reunited with Stranger co-star Shin Hye-sun for Netflix's The Art of Sarah (2026), playing detective Park Mu-gyeong in the Kim Jin-min-directed mystery thriller. Off screen, Lee is known for philanthropic work: he donated his full fee from Naked Fireman to the South Korea Fire Service and was named Honorary Firefighter by the President of South Korea in 2020.
