The 2022 Mid-Season Invitational was the seventh Mid-Season Invitational (MSI), a Riot Gamesorganised tournament for League of Legends, a multiplayer online battle arena video game. The tournament was the culmination of the 2022 Spring Split and the first interregional competition of Season 12.
11 of the 12 premier League of Legends leagues had a team representing them; the LCL was not participating due to the Spring Split being cancelled as a result of the 2022 Russian invasion of Ukraine. The competition continued the same format that was introduced during MSI 2021. The minimum prize pool was 250,000.
"Set It Off" was the tournament's theme song, put together by DPR Live, and DPR Cline.
The tournament was hosted in Busan, South Korea, from 10 to 29 May 2022. The Group Stage was held in the Busan Esports Arena, while the Rumble Stage and Knockout Stage was held in the Busan Exhibition and Convention Center (BEXCO) Exhibition Hall 1 in Busan. Due to COVID-19 pandemic in mainland China, the qualified team from LPL competed remotely from China, in the team's training facility.
Defending champion Royal Never Give Up from China defeated T1 from South Korea 3–2 in the final, winning their third MSI title.
