Jung Chan-Sung (born March 17, 1987), often anglicised to Chan-Sung Jung, is a South Korean mixed martial artist and kickboxer currently competing in the Ultimate Fighting Championships. His nickname "The Korean Zombie" comes from his ability to continue to move forward and fight aggressively, even after taking heavy blows. He made his professional debut in June 2007 and in December the same year he won a lightweight tournament arranged by Pancrase Korea. In 2008 he won both his fights for Japanese promotion DEEP. He then entered the 2009 Sengoku Featherweight Grand-Prix where he won his first-round fight but ended up getting eliminated from the tournament by the eventual winner Masanori Kanehara. Jung Chan-Sung is currently ranked #4 by ESPN and #10 by Fight Matrix in the featherweight division.

Born in Pohang, South Korea in 1987, Jung moved to Nam Yang Ju, a satellite city of Seoul when he was in his mid teens. Due to his slight stature and his rural birthplace, he was bullied constantly by his classmates. Jung got into many fights because of the bullying and usually lost. When his aunt could no longer stand to see Jung's predicament, she took him to a nearby Hapkido gym.
