Yoo Sang-chul (; 18 October 1971 – 7 June 2021) was a South Korean football player and manager. Yoo was regarded as one of the greatest South Korean midfielders of all time. He was selected as a midfielder of the 2002 FIFA World Cup All-Star Team and K League 30th Anniversary Best XI. Club career In 1994, Yoo joined a K League club Ulsan Hyundai Horang-i, and was selected as a defender of the K League Best XI right after his first season. In 1996, he won the 1996 K League with Ulsan. In 1998, he won the K League scoring title, scoring 14 goals in 20 games, and was named as a midfielder in the K League Best XI.

With only eight matches left in the 2002 season, he scored nine goals, helping Ulsan move from a mid-table position to a title challenge, finishing in second place. That season, he picked up another Best XI award as a forward, after finishing with the third-most goals in the league. He was one of only two players in K League history to have been included in all three outfield positions of the Best XI.
