The 2021 Fight for the Fallen was a professional wrestling television special produced by All Elite Wrestling (AEW). It was the third annual Fight for the Fallen charity event and took place on July 28, 2021, at the Bojangles Coliseum in Charlotte, North Carolina as a special episode of Wednesday Night Dynamite on TNT in the United States. For the event's charitable cause, it helped support victims of domestic violence and sexual assault survivors. It was also the third and last event in AEW's "Welcome Back" tour, which celebrated AEW's resumption of live touring during the COVID-19 pandemic.

Six matches were contested at the event. In the main event, Chris Jericho defeated Nick Gage in a No Rules match. In other prominent matches, Lance Archer retained the IWGP United States Heavyweight Championship against Hikuleo, and The Elite (Kenny Omega, Matt Jackson, and Nick Jackson), and The Good Brothers (Doc Gallows and Karl Anderson) defeated Adam Page and The Dark Order (Evil Uno, Stu Grayson, John Silver, and Alex Reynolds) in a 10-man tag team elimination match, preventing Page and The Dark Order from challenging for the AEW World Championship and AEW World Tag Team Championship, respectively.

Fight for the Fallen is a professional wrestling charity event held annually in July by All Elite Wrestling (AEW) since 2019. For the 2021 event's charitable cause, which was the third Fight for the Fallen event, AEW partnered with Safe Alliance, a non-profit organization dedicated to providing hope and healing for domestic violence and sexual assault survivors. In addition to AEW donating US$100,000 to Safe Alliance, a percentage of proceeds from the limited-edition Fight for the Fallen T-shirts were also donated.

Due to the COVID-19 pandemic that began effecting the industry in mid-March 2020, AEW held the majority of their programs from Daily's Place in Jacksonville, Florida; these events were originally held without fans, but the company began running shows at 10–15% capacity in August, before eventually running full capacity shows in May 2021. Also in May, AEW announced that they would be returning to live touring, beginning with a special episode of Dynamite titled Road Rager on July 7, which kicked off the "Welcome Back" tour. Fight for the Fallen was scheduled as the third and last event of the "Welcome Back" tour and like the 2020 event, it was held as a special episode of Dynamite. It took place on July 28, 2021, in Charlotte, North Carolina at the Bojangles Coliseum.

Fight for the Fallen featured professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines, written by AEW's writers. Storylines were produced on AEW's weekly television program, Dynamite, the supplementary online streaming shows, Dark and Elevation, and The Young Bucks' YouTube series Being The Elite.

The event opened with The Elite (Kenny Omega, Matt Jackson, Nick Jackson, Doc Gallows and Karl Anderson) taking on Adam Page, Evil Uno, Stu Grayson, John Silver and Alex Reynolds in a 10-man tag team elimination match. Kenny Omega and The Elite entered in basketball jerseys, as the "Elite Squad", to "Get Ready for This" in reference to Space Jam to promote Space Jam: A New Legacy starring LeBron James, Jeff Bergman, Eric Bauza and Zendaya Coleman. Since The Elite won, Adam Page could not challenge for the AEW World Championship. According to Being The Elite, the special entrance was a gift to Nick Jackson, who celebrated his birthday the day of the show.

After the opening match, Taz held a championship celebration for Ricky Starks, with a band playing live music. The celebration was interrupted by Brian Cage.

Next, FTR faced Santana and Ortiz. The match had to finish early after Cash Wheeler suffered an injury.
