The Mid-Season Invitational is League of Legends' second-most prestigious international tournament, the midyear summit where the best teams from every region clash for the second global trophy of the season. Launched in 2015, MSI has crowned ten champions across ten editions (the 2020 edition was cancelled due to the COVID-19 pandemic) — a history shaped by the LPL's early dominance, Europe's lone miracle run, RNG's record three titles, and Gen.G's recent back-to-back. Here's every MSI winner, year by year, with the scores, venues, rosters and storylines that defined each edition.
