Rift Rivals (RR) was a series of cross-regional League of Legends tournaments organized by Riot Games from 2017–2019.^[1][2] Rift Rivals was five concurrent tournaments where related regions would be pitted against each other. Teams who placed the best in the Spring Split (or other opening season) of the year were invited to a tournament against another region's top teams.^{[citation needed]} In 2019 Rift Rivals, the event was narrowed to only the two largest tournaments: the LCS (NALCS) vs. the LEC (EULCS) for North America vs. Europe, and the LPL vs. LCK vs. LMS-VCS for South Korea / China / Taiwan / Vietnam.

Due to the COVID-19 pandemic, 2020 Rift Rivals was canceled by Riot, as the originally scheduled timeslot in July 2020 was replaced by a delayed Mid-Season Invitational (MSI). Riot additionally announced it would "sunset" the tournaments.^[3]
