2020 Major League Baseball postseason

The 2020 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 2020 season. Due to the COVID-19 pandemic, the league played only a 60-game season, and an expanded 16-team postseason tournament began on September 29, with games of all but the first round being played at neutral sites. A new three-game Wild Card series was added as the opening round of this postseason due to the shortened season caused by the pandemic; it would become a permanent addition to the postseason format starting in 2022.

The postseason began on September 29, and ended on October 27. The World Series began on October 20 at Globe Life Field in Arlington, and ended on October 27, with the Los Angeles Dodgers defeating the Tampa Bay Rays in six games to win their first title since 1988. It was the Dodgers' seventh title in franchise history.
