NXT TakeOver: Stand & Deliver was a 2021 two-part professional wrestling event produced by WWE for its NXT brand division, airing as a television special and a pay-per-view (PPV) and livestreaming event. It was the 34th NXT TakeOver, as well as the inaugural Stand & Deliver, and it took place during WrestleMania 37 week on April 7 and 8, 2021, from the Capitol Wrestling Center, hosted at the WWE Performance Center in Orlando, Florida. It was the only TakeOver to take place over the span of two nights. The first night aired as a special episode of NXT on the USA Network, making it the only TakeOver to air on television as well as the final NXT broadcast on Wednesdays before moving to Tuesdays on April 13, while the second night aired via PPV. Both nights were also simulcast on WWE's livestreaming services; internationally, it was available through the WWE Network, while in the United States, it was the first WWE in-ring event to livestream on Peacock, following the shutdown of the standalone American WWE Network on April 4.

The card consisted of 12 matches evenly divided across both nights, including one match on the pre-show for each night. In the main event for Night 1, Raquel González defeated Io Shirai to win the NXT Women's Championship. Other prominent matches included Walter defeating Tommaso Ciampa to retain the NXT United Kingdom Championship and MSK (Wes Lee and Nash Carter) defeated Grizzled Young Veterans (James Drake and Zack Gibson) and Legado Del Fantasma (Raul Mendoza and Joaquin Wilde) to win the vacant NXT Tag Team Championship. Two matches were promoted as main event matches for Night 2. In what was the final match on the card, Kyle O'Reilly defeated Adam Cole in an unsanctioned match. In the penultimate match that was promoted as the other main event match, Karrion Kross defeated Finn Bálor to win the NXT Championship. In another prominent match on the undercard which opened the event, Santos Escobar defeated Jordan Devlin in a ladder match to determine the undisputed NXT Cruiserweight Champion.

While the NXT TakeOver series was discontinued in September, the Stand & Deliver event continued on, with a second event scheduled for the following year to be held during WrestleMania 38 weekend. This in turn established Stand & Deliver as NXT's annual event held during WrestleMania week. This was also the only Stand & Deliver event to air as a television special, as well as the only to air on PPV, as beginning with the following year's event, NXT's major events became only available via WWE's livestreaming platforms.

NXT TakeOver was a series of professional wrestling events that began in May 2014, as WWE's NXT brand held its second WWE Network-exclusive event, billed as TakeOver. In subsequent months, the "TakeOver" moniker became the brand used by WWE for all of its major NXT events. While originally exclusive to the WWE Network, NXT TakeOver events also became available on traditional pay-per-view (PPV) beginning with TakeOver 31 in October 2020.

Announced during the March 10, 2021, episode of NXT, Stand & Deliver was scheduled as the 34th NXT TakeOver event. It was also the only two-night TakeOver, airing on April 7 and 8, 2021, subsequently being the only TakeOver to be held on a Wednesday and Thursday night. Both nights aired on the WWE Network, making it the first WWE in-ring event to air on Peacock's WWE Network channel in the United States after the shutdown of the standalone version of the American WWE Network on April 4. The first night was also simulcast in NXT's normal timeslot on the USA Network, making it the only TakeOver to air on USA and on cable television. This was also the final NXT event to air in the Wednesday night timeslot, as NXT began airing on Tuesdays on April 13. The second night aired on traditional PPV in addition to the livestreaming platforms. Guitarist Nita Strauss performed "The Star-Spangled Banner" on Night 1, while musician Poppy performed her song "Say Cheese" on Night 2.

As a result of the COVID-19 pandemic that began affecting the industry in mid-March 2020, WWE had to present the majority of its programming from a behind closed doors set. NXT's programming was initially held at NXT's home base of Full Sail University in Winter Park, Florida. In October 2020, NXT's events were moved to the WWE Performance Center in Orlando, Florida, featuring the "Capitol Wrestling Center" setup, an homage to the Capitol Wrestling Corporation, the predecessor to WWE. Like the WWE ThunderDome utilized for Raw and SmackDown's programming, LED boards were placed around the Performance Center so that fans could attend virtually, while additionally, friends and family members of the wrestlers were in attendance, along with a limited number of actual live fans, divided from each other by plexiglass walls.

For TakeOver: Stand & Deliver, seating capacity was increased at the Capitol Wrestling Center, with extra rows of seats being added, and the plexiglass dividers being removed. Fans, however, were still required to wear masks, and were given free COVID tests prior to entering, with a negative test needed to enter.

The card comprised a total of 12 matches evenly divided between the two nights, which included one pre-show match each night. The matches resulted from scripted storylines. Results were predetermined by WWE's writers on the NXT brand, while storylines were produced on WWE's weekly television program, NXT.
