The Boston Red Sox are a Major League Baseball (MLB) team based in Boston, Massachusetts. They have competed in the American League (AL) since it was founded in 1901, and in the AL East division since it was formed in 1969. Note that before 1908, the team was known as the Boston Americans. The list below documents players (by careers and seasons) and teams (by seasons) that hold particular club records.

Note that these records reflect statistics only for a player's tenure with the Red Sox. For example, David Ortiz hit a total of 541 home runs during his MLB career; 483 with the Red Sox and 58 with the Minnesota Twins^[1]—thus, Ted Williams' 521 home runs, all hit with the Red Sox, is the team record. Similarly, the team record for wins with the Red Sox is 192, accomplished both by Roger Clemens and Cy Young, who had major league career win totals of 354 and 511, respectively.

Note that "rate" categories (such as batting average or earned run average) have thresholds (such as a minimum number of at bats or innings pitched) for eligibility.

The below tables have been updated with records through the 2020 season.

Note: games behind (GB) applies to non-first-place seasons, while games ahead (GA) applies to first-place seasons. The 2005 Red Sox, who finished in a tie for first in the American League East and were declared the Wild Card team based on head-to-head records, are not included in either category.

† These categories exclude the 2020 team that played a 60-game season; the team won 24 games and lost 36 games (a .400 winning percentage); scored 292 runs and allowed 351 runs; and played without fans in attendance due to the COVID-19 pandemic.

‡ The 1961 and 1985 teams each had a tie game during their 162-game schedule that was subsequently replayed; the 1978 team played a tie-breaker game at the end of their 162-game schedule.
