The 1980 Major League Baseball postseason was the playoff tournament of Major League Baseball for the 1980 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, both the New York Yankees and Kansas City Royals were making their fourth postseason appearance in the past five seasons.
In the National League, the Philadelphia Phillies also returned for the fourth time in the past five seasons, and the Houston Astros made their first postseason appearance in franchise history.
All four teams would return during the expanded 1981 postseason, as due to the lockout-shortened season, the season was split in half and the division leaders during each half qualified for the postseason. They would also appear in the expanded 2024 postseason.
The playoffs began on October 7, 1980, and concluded on October 21, 1980, with the Phillies defeating the Royals in six games in the 1980 World Series. This was the first championship in franchise history for the Phillies.
