The 2021 Oakland Athletics season was the 121st season for the Oakland Athletics franchise, all as members of the American League. It was also their 54th season in Oakland, which equaled the amount of seasons that they played in their original city of Philadelphia. It would ultimately be their final season with a winning record as an Oakland based franchise. The team would move to Sacramento in 2024 in anticipation for their move to Las Vegas in 2027.
