Byun Yo-han (born April 29, 1986) is a South Korean actor celebrated for his depth, expressive eyes, and mastery across film, television, and even musical theater. Unlike many stars who debut in mainstream projects, he meticulously built his career on the foundation of the independent film scene.

Byun Yo-han is an alumnus of the prestigious Korea National University of Arts (KNUA), a training ground for many of Korea’s top actors. During his student years, he dedicated himself to the craft, appearing in over 30 short and independent films starting in 2011. This period gave him the experience to tackle nuanced, unconventional roles early in his career, such as his lead performance in the independent hit film Socialphobia (2015).

His professional breakthrough came in 2014 with the cable television series, Misaeng: Incomplete Life. Playing Han Seok-yool, the overly talkative, slightly eccentric, but ultimately deeply empathetic intern with long, messy hair, Byun captured the imagination of the public. He won the Best New Actor award at the APAN Star Awards, launching him from an unknown indie darling into a recognized television star.

Following Misaeng, Byun quickly cemented his status as a talented lead actor in historical dramas, a genre that demands powerful presence and technical skill.

Six Flying Dragons (2015–2016): He took on the epic role of Ddang-sae / Lee Bang-ji, a tragic figure who becomes the legendary master swordsman. The demanding physical and emotional scope of the 50-episode sageuk earned him critical praise and an Excellence Award at the SBS Drama Awards.

Mr. Sunshine (2018): In one of the highest-rated dramas in cable history, Byun starred as Kim Hee-sung, the wealthy, sensitive fiancé to the female lead. His portrayal of a man trapped by his family's dark history and the era's changing politics showcased a lighter, yet profoundly melancholic, side to his acting.

While maintaining a strong television presence, Byun Yo-han consistently returned to film to challenge himself with diverse characters.

In 2021, he starred in the black-and-white historical drama The Book of Fish, delivering a standout performance as Chang-dae, a zealous Confucian scholar. This role earned him multiple nominations for Best Actor.

His film career reached a new peak with the 2022 naval blockbuster, Hansan: Rising Dragon, where he played the pivotal antagonist, Wakizaka Yasuharu, a cunning Japanese commander and rival to Admiral Yi Sun-sin. Byun's portrayal was widely praised for its intensity, leading him to win the Best Supporting Actor prize at prestigious ceremonies including the Baeksang Arts Awards, Blue Dragon Film Awards, and Grand Bell Awards.

Most recently, Byun Yo-han has starred in the Disney+ political drama Uncle Samsik (2024) and the dark thriller series Black Out (2024), continuing to demonstrate his preference for complex, character-driven narratives.

Byun Yo-han’s career is defined by his versatility and his deep commitment to the emotional truth of every role, making him one of South Korea's most trusted and acclaimed contemporary actors.
