2025 Boston Red Sox season

The 2025 Boston Red Sox season was the 125th season in Boston Red Sox franchise history, and their 114th season at Fenway Park. Alex Cora was the team's on-field manager, in the fifth season of his second stint in that role. The team opened the regular season in an away game against the Texas Rangers on March 27, and concluded at home against the Detroit Tigers on September 28.

On June 15, the Red Sox traded third baseman/designated hitter Rafael Devers to the San Francisco Giants. Devers was the last remaining player from the 2018 World Series-winning roster.

The Red Sox clinched their first postseason berth since 2021 on September 26, as they faced their longtime rivals, the New York Yankees, in the Wild Card Series. However, they were defeated by the Yankees in three games - their first postseason series loss against the Yankees since the 2003 ALCS.

The Boston Red Sox drew an average home attendance of 34,277, the 10th-highest of all MLB teams.
