The South Korean football league system contains two professional leagues, two semi-professional leagues, and various amateur leagues for Korean football clubs.

The highest level of football in South Korea is the K League 1, which was founded in 1983. K League 2 was founded in 2013 and is currently a second division. Below the level of the professional leagues are the semi-professional K3 League, which was founded in 2007 and refounded in 2020, and the K4 League, which was founded in 2020, and serve as the third division and fourth division, respectively.

There was no avenue for progression between any of the leagues until 2012, when the K League 2 was founded.

System by period

Korean National Semi-Professional Football League was a semi-professional football league between corporate teams in South Korea from 1964 to 2002. In 1983, with the establishment of K League which is a professional league, Semi-professional League became the second tier and remained until 2002 before Korea National League was officially founded in 2003. The third tier K3 League was founded as an amateur league in 2007, and became the fourth tier after K League 2, the second division of the professional league, was founded in 2013. K3 League also divided into the Advanced and the Basic, and they became semi-professional leagues with new names, K3 League (semi-professional) and K4 League, after the merger of National League in 2020. South Korean leagues are using systems of promotion and relegation in each of three classes: professional, semi-professional and amateur; but there are still no promotion and relegation between classes.
