The 2023 LCK season was the twelfth season of South Korea's LCK, a professional esports league for the MOBA PC game League of Legends. The season was divided into two splits: Spring and Summer. The Spring Split began on 18 January and culminated with the playoff finals on 9 April 2023. The Summer Split began on 7 June and culminated with the Summer Split finals on 20 August 2023.
The Spring Split winners, Gen.G, and runners-up, T1, qualified for the 2023 Mid-Season Invitational. Gen.G also won the Summer Split, directly qualifying them for the 2023 World Championship. T1 qualified for the 2023 World Championship via Championship Points, while both KT Rolster and Dplus Kia also qualified for the 2023 World Championship through the regional qualifier.

The regional qualifier was a tournament consisting of the top four teams in the LCK based on championship points that had not directly qualified for the 2023 World Championship. The top two teams faced off, and the winner earned a spot in the World Championship. Simultaneously, the bottom two teams played against each other, with the losing team being eliminated. The remaining two teams then competed for the last LCK spot in the 2023 World Championship.[9]
