List of Major League Baseball 100 win seasons

Over the course of 127 seasons (from 1892 to 2019 excluding 1994), 109 teams have won 100 or more games in a single Major League Baseball season. While this makes the feat a relatively common occurrence, the 100-win threshold remains the hallmark of the best teams in a given season.

While there have been 23 seasons with two or more 100-win teams, only eight times have at least three teams finished at or above the mark, and 2019 has been the only instance of four teams finishing at or above the 100-win threshold.

The 2018 season was the first time either league had more than two teams win 100 or more games in the same season; the Boston Red Sox, Houston Astros, and New York Yankees of the American League each won 100 or more games. There were no 100-win teams in the National League that season. The 2019 season marked the first time four Major League teams won 100 or more games, with the American League's Houston Astros, New York Yankees, and Minnesota Twins winning their divisions with at least 100 wins, and the Los Angeles Dodgers of the National League doing the same.

On eight occasions, the level of high-quality competition within a league or division has resulted in a team winning 100 games but still failing to qualify for postseason play. Six of these eight seasons occurred before the start of the two-division league structure and expanded playoff format introduced in 1969, but none have occurred since the first year under the Divisional Series format in 1995.[1]

With the Divisional Series and Wild Card format in place today, it is extremely unlikely for a team with a 100-win regular season to fail to qualify for at least a Wild Card berth. Only the 2001 Oakland Athletics and the 2018 New York Yankees made the playoffs as 100-win Wild Card teams.[2]

The following teams missed the postseason despite winning 100 games during the regular season:

• 1909 Chicago Cubs (104–49) (.680): Finished 2nd in NL
• 1915 Detroit Tigers (100–54) (.649): Finished 2nd in AL
• 1942 Brooklyn Dodgers (104–50) (.675): Finished 2nd in NL
• 1954 New York Yankees (103–51) (.669): Finished 2nd in AL
• 1961 Detroit Tigers (101–61) (.623): Finished 2nd in AL
• 1962 Los Angeles Dodgers (102–63) (.618): Finished 2nd in NL
• 1980 Baltimore Orioles (100–62) (.617): Finished 2nd in AL East
• 1993 San Francisco Giants (103–59) (.636): Finished 2nd in NL West
