NXT The Great American Bash (2021)

The 2021 NXT The Great American Bash was the ninth Great American Bash professional wrestling event produced by WWE, and 23rd Great American Bash event overall. It was held exclusively for wrestlers from the promotion's NXT brand division. The event aired as a special episode of WWE's weekly television series NXT, broadcast on the USA Network. Unlike the previous year, which aired as a two-part event, the 2021 event was a one-night event that took place on July 6, 2021, at the Capitol Wrestling Center, hosted at the WWE Performance Center in Orlando, Florida. This was the second Great American Bash to air as an annual television special of NXT.

Four matches were contested at the event. In the main event, Adam Cole defeated Kyle O'Reilly.
