The Oakland Athletics were a Major League Baseball franchise that played in Oakland, California, from 1968 through the 2024 season. The team, a member of the American League West Division, played its home games at the Oakland Coliseum. During their time in Oakland, the Athletics amassed nine World Series championships, fifteen pennants, and seventeen division titles, making them a historically successful club in the American League. The franchise had previously relocated to Oakland from Kansas City in 1968, having originated in Philadelphia. Despite their on-field achievements, the team departed Oakland after the 2024 season due to issues with the aging stadium and difficulties securing funding for a new ballpark. They subsequently moved to West Sacramento in 2025 with plans for a permanent relocation to the Las Vegas metropolitan area, marking the end of major league sports in Oakland. The team's overall win-loss record in Oakland was 4,614–4,387–1. Seventeen former players were inducted into the National Baseball Hall of Fame, with some depicted in their Hall of Fame plaques wearing an Oakland Athletics cap.

The Athletics franchise has a history of movement, originating in Philadelphia before relocating to Kansas City in 1954 under Arnold Johnson. Following Johnson's death, Charlie Finley purchased the team and, despite initial promises to remain in Kansas City, began exploring new locations. Finley pursued various cities, including Dallas-Fort Worth, Louisville, and Atlanta, even agreeing to a name change to the "Kentucky Athletics" for a potential move to Louisville. These attempts were largely denied by American League owners. By 1964, Finley had also been denied permission to move the team to Oakland. However, in October 1967, Finley officially announced Oakland as the team's new home, receiving approval from AL owners to relocate for the 1968 season. This marked the beginning of the Athletics' tenure in Oakland, where they would play at the Oakland-Alameda County Coliseum.

The Athletics' period in Oakland saw the emergence of a dominant team known as the "Swingin' A's" from 1971 to 1975. After two consecutive second-place finishes, the team captured the division title in 1971 and went on to win three consecutive World Series championships in 1972, 1973, and 1974. This era was characterized by a distinctive style, including vibrant green and gold uniforms and a "Moustache Day" promotion that encouraged players to grow facial hair, contrasting with the clean-shaven norms of other teams. The "Swingin' A's" played with strong pitching, defense, and clutch hitting, often overcoming teams with better regular-season records. Key players included Reggie Jackson, Catfish Hunter, Rollie Fingers, and Vida Blue. Despite their on-field success, relationships between players and owner Charlie Finley were often contentious, with Finley frequently intervening in team matters and player contracts.

The success of the "Swingin' A's" was not without its challenges. Owner Charlie Finley's management style often led to disputes, including interventions with star players like Reggie Jackson and Vida Blue. Finley's actions also impacted manager Dick Williams, who resigned after the 1973 World Series amidst controversy involving player Mike Andrews. The team also faced significant player defections due to free agency; pitcher Catfish Hunter became a free agent after Finley failed to meet contract obligations, subsequently signing with the Yankees. Finley's dissatisfaction with attendance in Oakland during championship years also led him to consider further relocations. Ultimately, the team's departure from Oakland after the 2024 season was attributed to the aging Oakland Coliseum and the inability to secure public funding for a new ballpark, concluding a 56-year history in the city.
