The South Korea national football team represents South Korea in men's international football and is governed by the Korea Football Association. 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 Asian team to reach the semi-finals when they co-hosted the 2002 tournament with Japan. South Korea also 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 FIFA World Cup, often simply called the World Cup, is an international association football competition among the senior men's national teams of the members of the Fédération Internationale de Football Association (FIFA), the sport's global governing body. The tournament has been held every four years since the inaugural tournament in 1930, with the exception of 1942 and 1946 due to the Second World War. The reigning champions are Argentina, who won their third title at the 2022 tournament.
