The 2007 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 2007 season. The winners of the 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 made their thirteenth straight postseason appearance, the Boston Red Sox returned for the fourth time in five years, the Cleveland Indians returned for the first time since 2001, and the Los Angeles Angels of Anaheim returned for the fourth time in six years.
In the National League, the Arizona Diamondbacks made their third postseason appearance in the last eight years, the Chicago Cubs made their second appearance in five years, the Colorado Rockies made their second postseason appearance in franchise history and first since 1995, and the Philadelphia Phillies returned to the postseason for the first time since 1993. This would be the first of five consecutive postseason appearances for the Phillies, a streak which lasted until 2011.
The postseason began on October 3, 2007, and ended on October 28, 2007, with the Red Sox sweeping the Rockies in the 2007 World Series. It was the seventh title won by the Red Sox franchise. This would be the last time until 2024 in which both teams who made the previous year's World Series failed to make the playoffs.
