The WWE ThunderDome was a bio-secure bubble created by the American professional wrestling promotion WWE, in partnership with the full-service fan experience company, The Famous Group. It was launched in August 2020 as a way for professional wrestling fans to attend WWE events virtually during the COVID-19 pandemic. The bubble was a videoconferencing crowd system and arena staging utilized for broadcasts of television shows and pay-per-views of the promotion's Raw and SmackDown brand divisions. It worked by users signing up days before an event, logging in and joining at their allocated call time to be seen on a screen at the event in real time. It was free of charge to spectate an event.

A bio-secure bubble, also known as a bubble, or hub city, was a hosting arrangement for sporting events that emerged during the COVID-19 pandemic, under which events were held at a centralized site, often behind closed doors, with strict quarantine and safety protocols in order to prevent the spread of COVID-19. A bubble was established for a single sports season, tournament, or for an ongoing series of events, allowing them to still be held and made available to broadcast audiences.
