Seo Jung-Won (born December 17, 1970 in Gwangju, South Korea) is a football player and coach from South Korea.
Nicknamed nalssen dori (speedy Gonzales-equivalent in Korean) in his native Korea, he was reportedly offered a contract from FC Barcelona and other European Club giants after his performances at the 1992 Summer Olympics.
Though Seo played mainly in the K League, he played for both FC Red Bull Salzburg and SV Ried as a forward and midfielder in the Austrian Bundesliga.
He made his professional debut in the South Korean K League for FC Seoul, then known as LG Cheetahs, and played at Suwon Samsung Bluewings from 1998 to 2004.
He has over 100 caps for his nation, and he was selected as a member of the South Korea national football team at the 1994 and 1998 FIFA World Cup, and the 1990, 1994, and 1998 Asian Games.
His contract with SV Ried expired in May 2006.
After South Korea national football team's head coach Pim Verbeek resigned in July 2007, Seo entered the list for the vacant managerial position for the South Korean national team.
From 2009 to 2010, he and his former national teammate and close friend, Hong Myung-Bo, worked together as a part of the coaching staff for the South Korea U-20 and U-23 team.
In 2010, Seo joined the coaching staff of the senior team under manager Cho Kwang-rae.
Since 2012, he has been a member of the coaching staff of the Suwon Samsung Bluewings, becoming the club's manager in 2013.
Under his tenure, the Bluewings finished the 2014 and 2015 seasons as runner-ups and won the Korean FA Cup in 2016.
The Cup Final was notable as it featured Suwon Samsung Bluewings and FC Seoul, one of the biggest K League rivalries.
The match went into extra time after FC Seoul scored a goal in the 93rd minute, leveling the aggregate score to 3-3 over two legs.
After a scoreless extra time period, the Cup Final was decided over penalties where Suwon Samsung Bluewings won 10-9.
The FA Cup was Seo's first silverware of his managing career.
