2000 Major League Baseball postseason

The 2000 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 2000 season. The winners of the League Division Series would move on to the League Championship Series to determine the pennant winners that face each other in the World Series.

In the American League, the New York Yankees returned to the postseason for the sixth straight time, the Chicago White Sox made their second appearance in the last seven years, the Seattle Mariners returned for the third time in six years, and the Oakland Athletics returned for the third time in eleven years.

In the National League, the Atlanta Braves made their ninth straight appearance in the postseason, the St. Louis Cardinals and San Francisco Giants both returned for the second time in five years, and the New York Mets returned for the second straight year. This postseason was notable in that it was the first time that both #1 seeds from the American and National Leagues failed to make it past the LDS.

The postseason began on October 3, 2000, and ended on October 26, 2000, with the Yankees defeating the Mets in five games in the 2000 World Series, also known as the "Subway Series" as both teams were from New York City. The Yankees completed a three-peat and won their 26th title in franchise history.
