The Korea National League was a South Korean semi-professional football league held annually from 2003 to 2019. It was considered the second-highest division of the South Korean football league system before the K League 2 was launched in 2013, and the third-highest division since then.
The Korea National League was officially founded in the name of K2 League in 2003 to execute a plan to professionalize the Korean National Semi-Professional Football League. The participating clubs of the National League had to have their hometowns unlike in the Semi-professional League era.
In 2006, the K2 League was re-branded as the Korea National League, and its champions were decided to promote to the K League. However, Goyang KB Kookmin Bank and Hyundai Mipo Dockyard, the champions of the 2006 and 2007 season respectively, judged that they couldn't derive benefit from their professionalization, and rejected their promotion.[1] The Korea Football Association and the K League Federation eventually prepared another project to found the second-tier professional league which is irrelevant to the National League.[2]
At the end of 2019, the Korea National League was absorbed into the K3 League.[3]
