The 2019–20 NBA season was the 74th season of the National Basketball Association (NBA). The regular season began on October 22, 2019, and originally was supposed to end on April 15, 2020. The 2020 NBA All-Star Game was played on February 16, at the United Center in Chicago, and was won by Team LeBron, 157–155.

However, the season was suspended on March 11 as a result of the COVID-19 pandemic. The playoffs were originally scheduled to begin on April 18, and end with the NBA Finals in June. At the time of the suspension, teams had played between 63 and 67 games.

All of these games took place in the NBA Bubble, an isolation zone specifically created for NBA operations at the ESPN Wide World of Sports Complex at Walt Disney World in Bay Lake, Florida.
