The Horror Show at Extreme Rules was a professional wrestling pay-per-view and WWE Network event produced by WWE for their Raw and SmackDown brand divisions. It was broadcast on July 19, 2020. While the majority of the event aired live from the WWE Performance Center in Orlando, Florida, the Wyatt Swamp Fight was pre-recorded on July 16–17. It was the twelfth event under the Extreme Rules chronology, and the first to have an altered title.
The event was originally scheduled to be held at the SAP Center in San Jose, California; however, the Santa Clara County government restricted public gatherings indefinitely due to the COVID-19 pandemic. As a result, and just like the majority of WWE's other shows since mid-March, the event was moved to the WWE Performance Center in Orlando, Florida.
