Mr. Sunshine (Korean: 미스터 션샤인) is a South Korean television series written by Kim Eun-sook and directed by Lee Eung-bok, starring Lee Byung-hun, Kim Tae-ri, Yoo Yeon-seok, Kim Min-jung, and Byun Yo-han. The series is set in Hanseong (present-day Seoul) in the early 1900s, and focuses on activists fighting for Korea's independence. It aired on tvN from July 7 to September 30, 2018, every Saturday and Sunday at 21:00 (KST), and premiered internationally on Netflix.

Upon its final broadcast, Mr. Sunshine was the third highest-rated series in Korean cable television history, with the last episode reaching 18.129% and netting an average rating of 12.955%, the highest average rating ever recorded for cable television at the time.

The series earned eight nominations and a Best Actor win for Lee Byung-hun at the 55th Baeksang Arts Awards.

While it received critical acclaim for cinematography and storytelling, as well as its strong female characters and portrayal of the lower classes, Mr. Sunshine was also subject to a certain amount of criticism for what was perceived as inaccurate representation of historical facts, with some accusing it of being "pro-Japanese", while others argued that it actually enforced stereotypes of the Japanese as villains and the Americans as heroes.
