The South Korea national football team (Korean: 대한민국 축구 국가대표팀; recognized as Korea Republic by FIFA) represents South Korea in men's international football and is governed by the Korea Football Association, a member of FIFA and the Asian Football Confederation (AFC).

South Korea has emerged as a major football power in Asia since the 1980s, having participated in ten consecutive and eleven overall FIFA World Cup tournaments, the most for any Asian country. Despite initially going through five World Cup tournaments without winning a match, South Korea became the first (and so far only) Asian team to reach the semi-finals when they co-hosted the 2002 tournament with Japan. South Korea also has won two AFC Asian Cup titles, and finished as runners-up on four occasions. Furthermore, the team won three gold medals and three silver medals at the senior Asian Games.

The team is commonly nicknamed the \"Reds\" by both fans and the media due to the color of their primary kit. The national team's supporting group is officially referred to as the Red Devils.
