The 2020 Backlash was the 15th Backlash professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held for wrestlers from the promotion's Raw and SmackDown brand divisions. The event aired on June 14, 2020, with all the matches taking place at the WWE Performance Center in Orlando, Florida. While the majority of the event aired live, the main event match between Edge and Randy Orton was pre-recorded on June 7. It was the first Backlash event held since 2018 and the final to be titled "Backlash" until 2023; the 2021 and 2022 events renamed the event series to "WrestleMania Backlash".

The event was originally scheduled to take place in Kansas City, Missouri; however, the event had to be relocated due to the COVID-19 pandemic. Like WWE's other shows since mid-March, Backlash was moved to the WWE Performance Center, though unlike the previous shows, Backlash was not announced until after the start of the pandemic, which made it WWE's first PPV event to be announced during the pandemic.

Seven matches were contested at the event, including one on the Kickoff pre-show. In the main event, Randy Orton defeated Edge in what WWE billed as "The Greatest Wrestling Match Ever". In the penultimate match, Drew McIntyre defeated Bobby Lashley to retain Raw's WWE Championship. In other prominent matches, Braun Strowman defeated The Miz and John Morrison in a handicap match to retain SmackDown's Universal Championship and Sheamus defeated Jeff Hardy.
