The 2021 PCS season was the second year of the Pacific Championship Series (PCS), a professional esports league for the MOBA PC game League of Legends.

The spring regular season was scheduled to begin on 5 February but was delayed to 19 February due to regional COVID-19 restrictions. The spring split concluded with the spring finals on 18 April.

The summer split began with the first day of the summer regular season on 9 July and concluded with the summer finals on 29 August.

PSG Talon was the PCS' representative at the 2021 Mid-Season Invitational and first seed at the 2021 World Championship. Beyond Gaming was the PCS' second seed at the 2021 World Championship.

The organisers of the PCS announced on 4 August 2020 that a promotion tournament would be introduced for the 2021 season to promote regional competitiveness.

Resurgence was relegated after a close series and Impunity Esports took their spot. Filipino team Liyab Esports, which finished ninth in both splits of the 2020 season, swept Panic Time from the Filipino qualifier in their relegation match and kept their spot.
