The 2020 Oakland Athletics season was the 120th season for the Oakland Athletics franchise, all as members of the American League, and their 53rd season in Oakland. The season saw the Athletics win the American League West for the first time since 2013.

On March 12, 2020, MLB announced that because of the COVID-19 pandemic, the start of the regular season would be delayed by at least two weeks in addition to the remainder of spring training being cancelled. Four days later, it was announced that the start of the season would be pushed back indefinitely due to the recommendation made by the CDC to restrict events of more than 50 people for eight weeks. On June 23, commissioner Rob Manfred unilaterally implemented a 60-game season. Players reported to training camps on July 1 in order to resume spring training and prepare for a July 24 Opening Day.

The A's hit two walk-off grand slams in their first 11 games of the season. They became the 17th team to hit two walk-off slams in the same year, the third team to hit two in an 11-game span and the fastest to do so from the start of the season.

On September 21, 2020, the A's clinched the American League West championship and then defeated the Chicago White Sox in three games in the 2020 American League Wild Card Series. This was the A's first postseason series victory since 2006, and they won their first winner-take-all postseason game since Game 7 of the 1973 World Series (snapping an MLB record nine-game losing streak in such contests). However, they lost to the Houston Astros in the 2020 American League Division Series.

The 2020 season was the Athletics' most recent postseason appearance. This was also the final postseason appearance as the Oakland Athletics, considering the team left Oakland after the 2024 season and has since rebranded as just "Athletics" on November 4, 2024.

Offseason

Rule changes For the 2020 season, MLB instituted several new rule changes including the following:

Single trade deadline – there will no longer be a waiver trade deadline later in the year. 26-man roster – rosters will expand from 25 players, but no team may carry more than 13 pitchers. Three-batter minimum for pitchers - a pitcher must face three batters in a game before they can be removed unless there is an injury or the end of an inning.

Further rule changes came into effect in response to the COVID-19 pandemic including the use of the DH in the National League, a shortened schedule, and starting extra innings with a runner at second base.
