Founded in February 2007, the inaugural K3 League season saw ten sides from across the nation compete for the title.
Slotting into the league set-up directly below the National League, the first ever champions of the third level of Korean football were Seoul United who clinched the 2007 championship with an aggregate victory over Hwaseong Sinwoo Electronics.
Membership of the K3 has expanded to 17 sides for 2009.

Unlike the first two seasons of the K3 League which operated on a two stage basis, the 2009 season will be a regular league season with each team playing each other twice for a total of thirty matches. The team at the top of the standings at the end of the season will be crowned champions.
Although final confirmation has still to be announced, the top sides in the K3 will qualify for the 2010 Korean FA Cup competition.
