The 1987 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 1987 season. The winners of each division advanced to the postseason and faced each other in a League Championship Series to determine the pennant winners that faced each other in the World Series.
In the American League, the Detroit Tigers were making their second appearance in the past five years, and the Minnesota Twins made their first postseason appearance since 1970. This would be Detroit’s last postseason appearance until 2006.
In the National League, the San Francisco Giants returned to the postseason for the first time since 1971, and the St. Louis Cardinals were making their third appearance in the last six years. This would be the last postseason appearance for the Cardinals until 1996.
The playoffs began on October 6, 1987, and concluded on October 25, 1987, with the Twins defeating the Cardinals in seven games in the 1987 World Series. It was the Twins' first title in Minnesota and their first since 1924, when they were known as the Washington Senators.
