The 1984 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 1984 season. The winners of each division advance to the postseason and face each other in a League Championship Series to determine the pennant winners that face each other in the World Series.
In the American League, the Detroit Tigers returned to the postseason for the first time since 1972, and the Kansas City Royals returned to the postseason for the sixth time in nine years.
In the National League, the Chicago Cubs were making their first postseason appearance since 1945, ending the longest postseason appearance drought in the league. Joining the Cubs were the San Diego Padres, who made their first postseason appearance in franchise history. This was San Diego’s last postseason appearance until 1996.
The playoffs began on October 2, 1984, and concluded on October 14, 1984, with the Tigers defeating the Padres in five games in the 1984 World Series. This was the first title since 1968 for the Tigers and their fourth overall.
