The Korea Professional Football League (K-League) is South Korea's top-flight professional club football league, with 14 member clubs.

The fourteen member clubs play each other twice in the regular season giving a total of 26 matches. The top six sides at the end of the regular season will enter the championship playoffs. In the first two matches, the third-placed team will face the sixth-placed team and the fourth-placed team will face the fifth-placed team, with the two winners then playing off for the right to face the second-placed team. The winner of that match will then progress to the two-legged championship playoff final where the first-placed side lie in wait, with the overall winner of the home and away series being crowned champions for 2007.


It is generally regarded as the Japanese equivalent to league cup competitions played in many countries such as the Football League Cup in England. Before the J. League Cup was created, the old Japan Soccer League had its own Japan Soccer League Cup since the 1976 season.
