The 2024 Mid-Season Invitational was the ninth Mid-Season Invitational (MSI), a Riot Games-organised tournament for League of Legends, a multiplayer online battle arena video game. The tournament was hosted in Chengdu, China, from May 1 to 19, 2024. All stages of the tournament were played at the Chengdu Financial City Performing Arts Center [zh].
JD Gaming from China were the defending champions, but failed to qualify for the event after losing to Top Esports in the lower bracket final of the 2024 LPL Spring Playoffs.
The event was won by Gen.G of South Korea after defeating the previous years' finalist, Bilibili Gaming of China, in the final with a score of 3–1. Gen.G became the second Korean team (after T1) to win an MSI title, and their win marked the first time a non-LPL (Chinese) team has won the event after three consecutive years of prior Chinese winners.
