The 1880 major league baseball season was contested from May 1 through October 1, 1880, and saw the Chicago White Stockings as the pennant winner of the fifth season of the National League. There was no postseason.

The 1880 season is known for the first two major league perfect games in history, as well as being the only perfect games in the 19th century. Thrown by Lee Richmond and John Ward, these two perfect games were thrown in the span of five days, the shortest amount of time between two perfect games (the next closest is currently 20 days between Dallas Braden's May 9 and Roy Halladay's and May 29, 2010 perfect games). A perfect game would not be seen again in the Major Leagues for 24 years when Cy Young threw his perfect game in 1904.

Over the off-season, the Cincinnati Reds and Syracuse Stars disbanded, and were replaced by the Cincinnati Stars and Worcester Worcesters. This would be the Stars' only major league season.
