The 1979 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 1979 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 Baltimore Orioles returned to the postseason for the first time since 1974, and the California Angels made their first postseason appearance in franchise history. In the National League, the Pittsburgh Pirates made their sixth postseason appearance in the past decade, along with the Cincinnati Reds.
This was the first postseason since 1975 to not feature either the New York Yankees, Kansas City Royals, Philadelphia Phillies, or Los Angeles Dodgers. The former three teams returned in the following postseason, and all four returned in the expanded 1981 and 2024 postseasons.
The playoffs began on October 2, 1979, and concluded on October 17, 1979, with the Pirates again defeating the Orioles in seven games in the 1979 World Series. The Pirates won their fifth and most recent title in franchise history.
