Halloween Havoc is a professional wrestling event currently produced by WWE. Since 2020, it has been held annually for the company's developmental brand, NXT. As the name implies, it is a Halloween-themed show held in October.
It was originally produced as an annual pay-per-view (PPV) event by World Championship Wrestling (WCW) from 1989 until 2000. The first two events were held when WCW was still affiliated with the National Wrestling Alliance (NWA) before WCW split from the NWA in January 1991. The final five events under WCW (1996–2000) were held at the MGM Grand Garden Arena in the Las Vegas suburb of Paradise, Nevada.
WWE—at that time still known as the World Wrestling Federation (WWF)—purchased the assets of WCW in March 2001. Nineteen years later in 2020, Halloween Havoc was revived as an annual event for WWE's NXT brand. The 2020, 2021, and 2023 events were held as television specials of the NXT program, while in 2022, it aired via WWE's livestreaming platforms. The 2023 edition was also a two-part event. In 2024, it returned to one night and to livestreaming.
