Running Man (Korean: 런닝맨) is a South Korean variety show, formerly part of SBS' Good Sunday lineup. It first aired on July 11, 2010. It is the longest running Korean variety show.

Running Man was originally classified as an "urban action variety"; a genre of variety shows in an urban environment. The MCs and guests were to complete missions at a landmark to win the race. The show has since shifted to a more familiar reality-variety show concept focused on games. It has garnered attention as being the comeback program for Yoo Jae-suk, the main MC of the program, after leaving Good Sunday's Family Outing in February 2010.

The show has become popular in other parts of Asia, and has gained online popularity among Hallyu fans, having been fansubbed into various languages, such as English, Persian, Spanish, Portuguese, French, Italian, Thai, Vietnamese, Chinese, Malay, Indonesian, Burmese, Arabic, Russian, and Turkish. The show has made it to the list of Business Insider's 20 TV Shows of 2016.

Since April 2017, Running Man is airing as the first part of Good Sunday at 4:50 pm KST and competing against KBS2's The Return of Superman and MBC's King of Mask Singer. Running Man previously aired at 6:25 pm KST on Sundays, as the second part of Good Sunday, competing against KBS2's 2 Days & 1 Night. The show celebrated its 11th anniversary on July 11, 2021, with 563 episodes, surpassing MBC's Infinite Challenge for the longest entertainment program in South Korea.
