NXT TakeOver: Stand & Deliver is an upcoming professional wrestling pay-per-view and WWE Network event, produced by WWE for their NXT brand division. It is scheduled to take place on April 7 and 8, 2021 at a venue that has yet to be announced. It will be the 34th NXT TakeOver event and the first to take place over the span of two nights. The first part will air in NXT's weekly Wednesday night timeslot on the USA Network, making it the first TakeOver to air on television. The second part is set to air the following night on pay-per-view, as well as the WWE Network, thus marking the first WWE event to air on Peacock's WWE Network channel in the United States following the shutdown of the aforementioned service's standalone American version on April 4. Tommaso Ciampa will be the first person not on the NXT UK (WWE brand) to challenge for the NXT United Kingdom Championship.
