The Rocket League Championship Series (RLCS) is an annual (previously semiannual) Rocket League Esports tournament series produced by Psyonix, the game's developer. It consists of qualification splits in North America, South America, Europe, Oceania, Middle East/North Africa, Asia, and Sub-Saharan Africa, and culminates in a playoff bracket with teams from those regions. The qualification rounds are played as an online round-robin tournament and the finals are played live in different cities. The Season 9 championship in 2020 and the Season X championship in 2021 were cancelled due to the COVID-19 pandemic, with region-based championships in their places.
Psyonix had observed the popularity of Rocket League matches on Twitch and other live streaming platforms by early 2016 and were looking to use the game more in Esports. In March 2016, Psyonix announced the first Rocket League Championship Series; the finals took place in June 2016 with a US$55,000 prize pool. The second season of the championship series took place in December 2016 with a $125,000 prize pool. A third series began in March 2017, with the $300,000 prize pool finals taking place three months later. In this season, two teams from the oceanic region were also invited to compete.
A second division, the Rocket League Rival Series (RLRS), was added in Season 4. The two teams finishing at the bottom of the RLCS and the two teams finishing at the top of the RLRS for each region play each other in a promotion tournament at the end of the season to determine if teams are promoted or relegated. At the advent of Season 5 in June 2018, Psyonix organised and managed the event alone. Previous to this, they partnered with Twitch. Season 6 started in September 2018 and featured a million dollar prize pool. For Season 7, Psyonix introduced South America as a new region. Season 8 took place in December 2019. The Season 9 championship was cancelled due to the COVID-19 pandemic, with winners of the regional championships being considered the champions. In July 2020, Psyonix announced a new format for the tenth season of RLCS, known as RLCS X. This format league play in favor of teams earning points through three regional splits, all culminating in three seasonal majors.
In September 2021, the RLCS 2021-22 season was announced, bringing in four new regions(Middle East North Africa, Asia Pacific North, Asia Pacific South and Sub-Saharan Africa), a more consistent tournament circuit similar to Season X, a $6,000,000 prize pool, 3 international Majors and an international World Championship.
