The WK League (Hangul: WK리그) is a semi-professional women's football league,^[1][2] run by the Korea Football Association (KFA) and the Korea Women's Football Federation (KWFF), which represents the sport's highest level in South Korea.^[3]

Icheon Daekyo won the inaugural edition of the WK League in 2009 and won two more titles in 2011 and 2012. Incheon Hyundai Steel Red Angels are the most successful team in the league, having won eleven consecutive titles since 2013.^[4]

During the regular season, contested from March to September, each team plays a total of 28 games, playing four times against each of the other seven teams. Teams receive three points for a win and one point for a draw. No points are awarded for a loss. Teams are ranked by total points.^[5]

In the case that teams are level on points, tie-breakers are applied in the following order:

1. Goal difference
2. Head-to-head results
3. Total goals scored
4. Total wins
5. Drawing lots

Then, the second and third-placed teams of the regular season face off in a one-legged semi-final, with the winners facing the first-placed team of the regular season in a two-legged championship game. The remaining teams are ranked from fourth to eighth.^[5]

The regular season was reduced to 21 games in 2020 and 2021 due to the COVID-19 pandemic in South Korea.^[6][7][8][9] A shortened season was maintained in 2022 due to the 2022 FIFA U-20 Women's World Cup and the 2022 Asian Games, and again in 2023 due to the 2023 FIFA Women's World Cup.^{[10][11][12][13]} The 2024 edition of the league saw a return to the 28-round regular season.^[14][15]
