The 1982 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 1982 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.
Every team from the 1981 postseason missed the playoffs this year, except the Milwaukee Brewers, who returned for the second straight year. The California Angels returned to the postseason for the second time in four years, the Atlanta Braves returned to the postseason for the first time since 1969, and the St. Louis Cardinals made their first postseason appearance of the divisional era. This would be the last postseason appearance for the Brewers until 2008.
The playoffs began on October 5, 1982, and concluded on October 20, 1982, with the Cardinals defeating the Brewers in seven games in the 1982 World Series. This was the first title since 1967 for the Cardinals and their ninth overall.
