Lee Chun-Soo (Korean: 이천수) is a retired football player from South Korea. In 2002, he joined Ulsan Hyundai FC.
He played as a forward for the national team during the 2002 World Cup, the 2004 Summer Olympics, and the 2006 World Cup.
In 2002, Lee scored seven goals in the K-League and made the World Cup squad. After the World Cup, he moved to Real Sociedad of Spain, becoming the first Korean to play in the Spanish La Liga. After a mediocre season, however, he was loaned to fellow Spanish side Numancia, before returning to Ulsan Hyundai Horang-i of South Korea's K-League.
Though Lee joined Ulsan mid-season, his performance proved to be invaluable to Ulsan's capture of the 2005 league, scoring a hat trick in the first leg of the finals. He was subsequently named the K-League's Most Valuable Player on 28 December 2005.
At the 2006 World Cup, he scored Korea's first goal with a free kick against Togo in a 2–1 win.
