2024 Major League Baseball postseason

The 2024 Major League Baseball postseason was the playoff tournament of Major League Baseball (MLB) for the 2024 season. In each of the two leagues – National and American – the three division winners and three wild card teams (the remaining teams with the best records) participated in the postseason, for a total of twelve teams. First was the best-of-three Wild Card Series, with the two division winners with the best records getting a first-round bye. Next was the best-of-five Division Series. The victors advanced to the best-of-seven League Championship Series to determine the pennant winners, the champions of each league. These two teams played each other in the best-of-seven World Series. The postseason began on October 1 and ended on October 30.

In the American League, the New York Yankees returned to the postseason for the seventh time in the past eight seasons, after missing the postseason last year. The Cleveland Guardians returned to the postseason for the seventh time in the past twelve seasons, the Houston Astros returned to the postseason for the eighth time in a row and the ninth in the past ten seasons, and the Baltimore Orioles returned for the second time in a row. The Detroit Tigers ended a decade of futility by returning to the postseason for the first time since 2014, ending the longest current playoff drought in Major League Baseball, which was tied with the Los Angeles Angels. The last team to make the postseason on the American League side were the Kansas City Royals, who clinched their first playoff berth since their 2015 championship season. The defending World Series champions, the Texas Rangers, were eliminated from postseason contention on September 20.

In the National League, the Milwaukee Brewers clinched their sixth appearance in the past seven seasons. Joining them were the Los Angeles Dodgers, who returned to the postseason for the twelfth consecutive time, which remains the longest active playoff streak in major North American professional sports. The Philadelphia Phillies returned to the postseason for the third time in a row, the San Diego Padres returned to the postseason for the third time in the past five seasons, the New York Mets returned to the postseason for the fourth time in the past ten seasons via the September 30th doubleheader against the Atlanta Braves, and the Braves clinched their seventh straight appearance via the second game doubleheader against the Mets.

With the Mets and Braves clinching, the Arizona Diamondbacks, the defending National League champions, were eliminated from postseason contention. This marked the first time since 2007 where neither team from the previous year's World Series appeared in the postseason.

In the Division Series, every series was tied 1–1 in the first two games for the first time in the history of the Major League Baseball postseason.

The postseason ended with the Dodgers defeating the Yankees in five games in the 2024 World Series. It was the Dodgers’ eighth championship in franchise history, tying the San Francisco Giants for the fifth most World Series championships.
