2002 Major League Baseball postseason

The 2002 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 2002 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 Anaheim Angels, formerly known as the California Angels, returned to the postseason for the first time since 1986. Joining them were the New York Yankees, who made their eighth straight postseason appearance, the Oakland Athletics, who returned for the third year in a row, and the Minnesota Twins, who made their first appearance since 1991.

In the National League, the San Francisco Giants returned for the second time in three years, the Arizona Diamondbacks returned for the third time in four years, the St. Louis Cardinals returned for the third straight time, and the Atlanta Braves made their eleventh consecutive appearance.

The postseason began on October 1, 2002, and ended on October 27, 2002, with the Angels defeating the Giants in seven games in the 2002 World Series to win their first World Series title in franchise history. This was the first World Series to feature both Wild Card teams from the American and National Leagues. It was also the last World Series to feature two teams from the same state.
