The 2020 Double or Nothing was the second annual Double or Nothing professional wrestling pay-per-view (PPV) event produced by All Elite Wrestling (AEW). It took place during Memorial Day weekend on Saturday, May 23, 2020, in Jacksonville, Florida. While the majority of the event aired live from Daily's Place, the main event match was pre-recorded from May 22–23 at the nearby TIAA Bank Field. It was the first event to feature the AEW TNT Championship. The event aired through traditional PPV outlets, as well as on B/R Live in North America and FITE TV internationally.

The event was originally scheduled to take place at the MGM Grand Garden Arena in Paradise, Nevada. The venue, however, canceled all events up through May 31 due to the COVID-19 pandemic. AEW moved the event to the Jacksonville Jaguars complex in Jacksonville, Florida, with most matches taking place at Daily's Place—an amphitheater adjacent to TIAA Bank Field—while the main event match took place in the stadium itself, subsequently being the first AEW event to take place in a stadium. It was also the first AEW PPV produced during the pandemic.

Nine matches were contested at the event, including one on The Buy In pre-show. In the main event, Matt Hardy and The Elite (Adam Page, Kenny Omega, Matt Jackson, and Nick Jackson) defeated The Inner Circle (Chris Jericho, Jake Hager, Sammy Guevara, Santana, and Ortiz) in a Stadium Stampede match, which was a cinematic match. In the penultimate match, Jon Moxley defeated Mr. Brodie Lee to retain the AEW World Championship. In other prominent matches, Hikaru Shida defeated Nyla Rose to win the AEW Women's World Championship, Cody defeated Lance Archer to become the inaugural TNT Champion, and in the opening bout, a debuting Brian Cage won the Casino Ladder Match. Additionally, the event featured an appearance from International Boxing Hall of Famer Mike Tyson, who presented the TNT Championship to Cody.
