The 2020 NBA Bubble was the bio-secure bubble at Walt Disney World in Bay Lake, Florida, near Orlando, that was created by the National Basketball Association (NBA) to protect its players from the COVID-19 pandemic during the final eight games of the 2019–20 regular season and throughout the 2020 NBA playoffs. 22 out of the 30 NBA teams were invited to participate with games being held behind closed doors at the ESPN Wide World of Sports Complex and the teams staying at Disney World hotels.

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.
