The K League was founded in 1983 as the Korean Super League, with five member clubs. The initial five clubs were Hallelujah FC, Yukong Elephants, POSCO Dolphins, Daewoo Royals, and Kookmin Bank FC. Hallelujah FC won the inaugural title, finishing one point ahead of Daewoo Royals to lift the crown.
In 1998, Korea's football league was reformed and renamed the K League (K League was official orthography by 2012). Since its creation, the league has expanded from an initial 5 to 16 clubs. Of the five inaugural clubs, only Yukong Elephants, POSCO Dolphins, and Daewoo Royals remains in the K League; Kookmin Bank FC dropped out of the league at the end of 1984, and Hallelujah FC followed the season after.
In 2013, K League introduced the division system, splitting the league into two divisions. The first division's name was K League Classic, the second division's name was K League Challenge and the comprehensive brand name was K League. The fact that both the first and second divisions had very similar names caused some degree of confusion and controversy. Beginning with the 2018 season, the first division was renamed to K League 1 and the second division to K League 2.
Below the K League 1 is the K League 2, and below the K League 2 is the National League, a closed semi-professional league established in 2003. The fourth level of football in South Korea is the K3 League.
On 5 October 2011, the league announced a plan to introduce a relegation system from the 2012 season, when two teams were relegated. In 2013, the bottom two teams were directly relegated, while the 12th team played a relegation playoff match against the winner of the newly-formed K League Challenge. From the 2013 season, as the number of teams of K League was reduced, only the 12th team is automatically relegated, with the 11th team playing a match against the winner of the K League 2 promotion playoffs.

At the inception of the K League in 1983, only two Brazilian players made rosters. At the time, rules allowed each club to have three foreign players and that the three could also play simultaneously in a game. From the 1996 season, each team had five foreign players among whom three could play in a game at the same time. Moreover, from the 2000 season to the 2002 season, the limit on foreign players was expanded seven but only three could play in a game at the same time. The limit was lower to five in 2003, four in 2005, and three in 2007. From the 2009 season, the number of foreign players went back up to four per team, including a slot for a player from AFC countries.
In the 1985 season, Piyapong Pue-on of Thailand led foreign players in the league in scoring and assists. Other leading players were Rade Bogdanović, who provided 10 goals and 10 assists in the 1996 season. Valeri Sarychev, the K League's most famous foreign goalkeeper, played in 320 league games from 1992 to 2004. He was eventually naturalized as a Korean citizen and given the Korean name Shin Eui-Son which means God's hand because of his stellar play.
In the 1990s, the trend was for the K League to get foreign players from Eastern Europe such as Rade Bogdanović, Radivoje Manic, Saša Drakulić and Denis Laktionov. From 2000, Brazilians became the K League's priority such as Tavares, Mota, Nádson, Adilson and Edu. Since 2009, players from AFC have been fairly popular, especially those from Australia, China, Japan and Uzbekistan.
