2021 Baltimore Orioles season

The 2021 Baltimore Orioles season was the 121st season in Baltimore Orioles franchise history, the 68th in Baltimore, and the 30th at Oriole Park at Camden Yards. With a final record of 52–110 (.321), the team significantly failed to improve on their 25–35 (.417) record from the previous year. The Orioles endured two different losing streaks of 14 or more between the middle and the end of May, as well as between August 3 and August 24. The Orioles pitching staff combined for an all-time franchise-worst earned run average (ERA) of 5.84 and yielded 911 earned runs in the season, which led MLB and was the most earned runs surrendered by a pitching staff since the 2001 Texas Rangers allowed 913 earned runs. According to Baseball Reference, 25 pitchers finished with negative wins above replacement (WAR), the most in MLB history. This broke the previous record of 22, which was set by the 2019 Orioles. All of the team's pitchers that made a start finished the season with a losing record. The Orioles were eliminated from playoff contention on August 28 with their loss to the Tampa Bay Rays. They suffered their 3rd 100+ loss season in four years with their loss to the Boston Red Sox on September 17. With the Orioles loss in the season finale against the Blue Jays, they suffered their second 110-loss season in team history; it was also the third such season in overall franchise history, going back to their time as the St. Louis Browns.

Despite the team's atrocious performance, Trey Mancini, who missed the 2020 season with colon cancer, won the AL Comeback Player of the Year award.
