The 2019 NXT TakeOver: WarGames was the 27th NXT TakeOver and the third annual NXT WarGames professional wrestling livestreaming event produced by WWE. It was held exclusively for wrestlers from the promotion's NXT brand division. The event aired exclusively on the WWE Network and took place on November 23, 2019, at the Allstate Arena in the Chicago suburb of Rosemont, Illinois as part of that year's Survivor Series weekend. It was also the first event to feature a women's WarGames match, which subsequently made it the first to have two WarGames matches on the same night. It was also the second TakeOver event in history in which the NXT Championship was not defended (after Respect in October 2015), and was the first which saw no title defenses on the card. The event was the first NXT TakeOver held following NXT's recognition as one of WWE's three main brands in September.

Five matches were contested at the event, including one on the Pre-Show. In the main event, Team Ciampa (Tommaso Ciampa, Keith Lee, Dominik Dijakovic, and Kevin Owens) defeated The Undisputed Era (Adam Cole, Bobby Fish, Kyle O'Reilly, and Roderick Strong) in a WarGames match while in the opening bout, Team Ripley (Rhea Ripley, Candice LeRae, Tegan Nox, and Dakota Kai) defeated Team Baszler (Shayna Baszler, Bianca Belair, Io Shirai, and Kay Lee Ray) in the first-ever women's WarGames match.
