The Pacific Championship Series (PCS) is a professional esports league for League of Legends teams competing in the Asia-Pacific.[a] Riot Games, the game's developer, created the league in 2019. This followed an announcement by Garena – the game's distributor in Taiwan, Hong Kong, Macau, and Southeast Asia – that it planned to merge the League of Legends Master Series (LMS) and League of Legends SEA Tour (LST) into a single tournament jointly run with Riot Games.
Initially, ten teams competed in the regular season, but this was reduced to eight teams in the 2024 spring season and finally seven in the 2024 summer season. In its final year of tier-one competition, the top six teams from the PCS regular season advanced to the playoffs and were joined by the top three teams from Japan and the top two teams from Oceania. Oceania became a part of the PCS region in 2022, with the League of Legends Circuit Oceania (LCO) being downgraded to a tier-two league secondary to the PCS. Japan followed suit the next year, with the League of Legends Japan League being similarly downgraded and integrated into the PCS.
Riot Games announced in 2024 that the League of Legends Championship Pacific (LCP) would replace the PCS as the Asia-Pacific's tier-one league from 2025 onward. The PCS, along with the LJL and VCS, would become the LCP's secondary leagues, with a path to promotion to the LCP.
