The 2021 Revolution was the second annual Revolution professional wrestling pay-per-view (PPV) event produced by All Elite Wrestling (AEW). It was broadcast on March 7, 2021. While the majority of the event aired live from Daily's Place in Jacksonville, Florida, the tag team Street Fight, which was produced as a cinematic match, was pre-recorded at an undisclosed location in Atlanta, Georgia. It was AEW's first PPV event held on a Sunday, as all of their previous PPVs were held on Saturdays. The event aired through traditional PPV outlets, as well as on B/R Live in North America and FITE TV internationally.

Nine matches were contested at the event, including one on The Buy In pre-show. In the main event, Kenny Omega defeated Jon Moxley in an Exploding Barbed Wire Deathmatch to retain the AEW World Championship. In the penultimate match, Darby Allin and Sting defeated Team Taz (Brian Cage and Ricky Starks) in a Street Fight, in what was both Sting's AEW in-ring debut and first match since competing at WWE's Night of Champions event in September 2015, coming out of retirement. In other prominent matches, The Young Bucks (Matt Jackson and Nick Jackson) defeated The Inner Circle (Chris Jericho and MJF) to retain the AEW World Tag Team Championship in the opening bout, and Hikaru Shida defeated Ryo Mizunami to retain the AEW Women's World Championship The event was also notable for the surprise appearances of Maki Itoh, Ethan Page, and Christian Cage, the latter two making their AEW debut.

The event drew an attendance of over 1,300 people, AEW's largest attended show during the COVID-19 pandemic up to that point, and continued the promotion's plans to begin admitting more spectators to events, as All Out drew 750 and Full Gear drew 1,000 fans.
