Halloween Havoc is a professional wrestling event currently produced by WWE. As the name implies, it is a Halloween-themed show held in October. It was originally produced as an annual pay-per-view (PPV) by World Championship Wrestling (WCW) from 1989 until 2000 as WWE—at that time still known as the World Wrestling Federation—purchased WCW in 2001. The 2000 event was the final Halloween Havoc until WWE revived the show for their NXTbrand division in 2020. The first four events were held when WCW was still affiliated with the National Wrestling Alliance. The final five events under WCW were held in the Las Vegas suburb of Paradise, Nevada, at the MGM Grand Garden Arena. In 2015, all WCW pay-per-views were made available on the WWE Network. In 2018, Las Vegas based company, KBN Inc. filed for the trademark of Halloween Havoc which according to the United States Patent and Trademark Office had been listed as "dead" since 2005.
On October 4, 2020, it was announced that WWE's NXT brand would revive Halloween Havoc as a special episode of the weekly NXT television program on October 28.
