The 2025 Detroit Tigers season was the team's 125th season and its 26th at Comerica Park. This was the Tigers' fifth season under manager A. J. Hinch. The Tigers improved their 86–76 record from the previous season by one win, and despite a strong first half that found them as much as 25 games over .500 (59–34 on July 8), the Tigers faltered severely in the second half, going 28–37 since the All-Star Game and only 7–17 in September. They gave up their division lead to the Cleveland Guardians, a team that was 15.5 games behind them in early July and 10.5 games back on August 31. Their collapse has been described as one of the worst in all of MLB history. Nevertheless, on September 27, the Tigers clinched a postseason berth for the second consecutive season with a 2–1 win over the Boston Red Sox. They finished with the same 87–75 record as the Houston Astros, but secured the last playoff spot by virtue of winning the head-to-head series.

The Tigers avenged last year's ALDS defeat to the Guardians by defeating them in the American League Wild Card Series, two games to one, and faced the second seed Seattle Mariners in the Division Series. Detroit repeated their 2024 ALDS performance, losing the series in five games. The fifth game extended to 15 innings, making it the longest winner-take-all game in MLB history.

The Detroit Tigers drew an average home attendance of 29,795.https://www.espn.com/mlb/attendance/_/year/2025
