League of Legends Champions Korea (LCK) is the primary competition for League of Legends esports in South Korea. Contested by ten teams, the league runs two seasons per year and serves as a direct route to qualification for the annual League of Legends World Championship. The LCK is administered in cooperation between Riot Games and KeSPA.
The league was formerly named League of Legends Champions before undergoing a major restructuring in late 2014, which saw a change in the competition's format and a rebranding to its current name. OGN reserved exclusive broadcasting rights of the league until 2016 when rights were split with SPOTV Games. In 2019, Riot Games took over the broadcasting of LCK. In 2021 the LCK franchised, and Challengers Korea (CK) and the LCK promotion tournament were discontinued.
Teams from the LCK have won the World Championship a record nine times, including five consecutive titles from 2013 to 2017.
