The 2021 Boston Red Sox season was the 121st season in the team's history, and their 110th season at Fenway Park. The team entered the offseason conducting a managerial search, after declining to bring back Ron Roenicke from the shortened 2020 season. On November 6, 2020, the team re-hired Alex Cora as manager; Cora had skippered the Red Sox in 2018 and 2019, then sat out 2020 serving a one-year suspension for his role in the Houston Astros sign stealing scandal in 2017.
