WK League

 ( Women's League ) 

In 2008, the KWFF launched an exhibition league as a pilot for the planned year-round league, with four teams participating in three rounds, to be held alongside pre-existing football tournaments. Daekyo Kangaroos won the exhibition league. Following the pilot scheme, it was announced that the WK League would be launched in 2009.

Due to the issue of securing stadiums in major cities, it was deemed too difficult to operate a home-and-away system. Instead, cities were selected to host a number of rounds each. The first edition of the league was contested by six teams over four rounds and 63 matches, including an all-star game and the championship final. Matches were held on Monday nights to avoid clashes with other professional sports.

The first match of the 2009 WK League took place on 20 April 2009 at Wolmyeong Sports Complex in Gunsan between Daekyo Kangaroos and Hyundai Steel, resulting in a 0–0 draw. Daekyo finished the regular season in first place and went on to win the championship final against Hyundai Steel to become the inaugural WK League champions.

In 2010, the South Korean government announced plans to invest in women's football, including the creation of two new clubs to compete in the WK League. Jeonbuk KSPO and Chungbuk Sportstoto were both formally launched ahead of the 2011 season, bringing the total number of teams in the league to eight. However, the following year the league was reduced to seven teams following the dissolution of Chungnam Ilhwa. From 2012 to 2016, the league continued with seven teams, meaning one team would sit out each round. In 2013, the WK League drew the attention of local and international media following claims by six clubs that Seoul WFC striker Park Eun-sun was in fact a man. It was reported that coaches from six teams threatened to boycott the 2014 league unless Park took a gender verification test. Seoul WFC accused their rivals of violating Park's human rights and demanded an apology. Park also received support from an online petition as well as Democratic Party politician Jun Byung-hun, who called for an investigation by the National Human Rights Commission. The six coaches involved claimed that the controversy was a private joke that had been leaked and blown out of proportion. Lee Sung-gyun of Suwon FMC and Yoo Dong-kwan of Goyang Daekyo resigned in the aftermath of the row. In February 2014, the National Human Rights Commission advised the Korea Football Association (KFA) to punish the coaches, but neither the KFA nor the league itself handed down any punishment and as a result, Park eventually left Seoul to join WFC Rossiyanka.

In 2015, the league began a home-and-away system for the first time, allowing teams to establish stronger connections with regional governments and fanbases.

Gyeongju KHNP WFC joined the league in the 2017 season, bringing the total number of teams back to eight.

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 play-off, 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.

The regular season was reduced to 21 games in 2020 and 2021 due to the COVID-19 pandemic in South Korea. 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. The 2024 edition of the league saw a return to the 28-round regular season.

The WK League is the only women's league in the country and as such there is no relegation system in place.

Following the expansion of the league in 2011, the all-star game was contested between "Team Gaia" (Goyang Daekyo, Busan Sangmu, Chungnam Ilhwa, Chungbuk Sportstoto) and "Team Athena" (Suwon FMC, Incheon Hyundai, Seoul WFC, Jeonbuk KSPO) and ended in a 9–6 win for Team Gaia, with six goals scored in the first half alone.

In 2012, the format changed once again, with teams divided into two based on their position in the league following the 9th round of the regular season. While players were previously selected based on coaches' recommendations, for the first time fans were able to vote for coaches and players to participate. In an effort to promote the WK League and women's football more widely, the all-star game also featured attractions and gimmicks such as an autograph signing event, unique goal celebrations, celebrity guests, and a goalkeeper taking a penalty kick. The "Blue Mir" team (Goyang Daekyo, Jeonbuk KSPO, Chungnam Ilhwa, Suwon FMC) won 5–4 against the "Red Mir" team (Hyundai Steel, Seoul WFC, Chungbuk Sportstoto, Busan Sangmu). The 2013 all-star game saw a 4–4 draw between team "Phenomenon" (Hyundai Steel, Jeonbuk KSPO, Suwon FMC, Busan Sangmu) and team "Fantasy Star" (Goyang Daekyo, Chungbuk Sportstoto, Seoul WFC), with elaborate pre-rehearsed goal celebrations such as dancing to Psy's hit song "Gentleman" and a portrayal of baseball player Hyun-jin Ryu's pitch.

The 2014 all-star game was due to be held on 2 June, but was cancelled following the sinking of the MV Sewol, with the KWFF stating that it would not be appropriate to hold such a festive event during a period of national mourning. The event did not take place in 2015 due to South Korea's participation in the 2015 FIFA Women's World Cup.

When the all-star game returned to the schedule in 2016, it had a new format. Rather than an exhibition match between two all-star teams from within the league, a WK League all-stars team selected by a technical committee played against 1. FFC Frankfurt in a friendly match held at Ulsan Stadium. The game finished as a 1–1 draw, and the WK League side won 5–3 in a penalty shoot-out.

In 2017, the all-star game was held after the end of the league season in November rather than during the mid-season break. The WK League all-star team, selected by fan vote, hosted INAC Kobe Leonessa at Incheon Namdong Stadium in a match that resulted in a 2–2 draw. The WK League side won the subsequent penalty shoot-out 4–2.

Following developments in inter-Korean relations, the KWFF hoped to invite a North Korean team for the 2018 all-star game, but an agreement could not be reached and the game was cancelled.

In 2019 and 2022, an all-star game was included in the league schedule with the date, location, and teams listed as "undecided".
