2021 Hangzhou Spark season

The 2021 Hangzhou Spark season was the third season of Hangzhou Spark's existence in the Overwatch League. After their first two games, the Spark released head coach Hwang "paJion" Ji-sub, who became the head coach in the middle of the 2020 season, and promoted Hwang "Andante" Jae-hong to interim head coach. However, he was also released in the second half of the regular season. The Spark finished the regular season in fifth place in the Eastern region. Their season ended after they were eliminated in the play-in tournament tournament semifinals, losing to the Philadelphia Fusion.

Roster changes
The Spark entered free agency with five free agents, all of which became free agents due to the Spark not exercising the option to retain the player for another year.

The Spark's final acquisition of the offseason came on November 19 with the signing of Seo "SeoMinSoo" Min-soo, a damage player who is considered one of the best flex damage players in the league with a "very deep pool of heroes to draw from," although he did not compete in the 2020 season.

Outside of the Spark's free agents, tank player Yu "QoQ" Sung-jun was released from the team on November 12, 2020.
