2025 Mid-Season Invitational
The 2025 Mid-Season Invitational was the tenth iteration of the Mid-Season Invitational, a Riot Games–organized tournament for League of Legends, a multiplayer online battle arena video game. The tournament was played in Vancouver, Canada from June 27 to July 12, 2025, and was Canada's first hosting of an international League of Legends competition. It was also the first edition of the tournament to feature the Fearless Draft format, and the first to be staged under the game's new competitive esports calendar since 2025.
Nineteen best-of-five series were played during the tournament, nine of which reached a fifth and deciding game, setting the record for the most number of game five's in any international League of Legends competition, surpassing the six game-fives witnessed during the 2021 League of Legends World Championship.

The two qualified teams from the play-in stage joined the top two seeds from the LCK, the first seeds from the LCP, LEC, and LPL, and the LTA North champions, where they competed in a double-elimination bracket.

The 2025 Mid-Season Invitational was the first edition of the tournament to adopt the Fearless Draft format. Fearless Draft is an evolution of the traditional pick/ban system wherein champions picked in previous games of a best-of-series become unavailable for both teams in subsequent games. While Fearless Draft was originally intended to only be used during the first split of the season, Riot Games announced prior to the First Stand Tournament final that the rules would apply for the rest of the year after it received "overwhelming" positive feedback during the period.
