The 2019 Oakland Athletics season was the 119th season for the Oakland Athletics franchise, all as members of the American League, and their 52nd season in Oakland. The A's clinched a spot in the ALWC Game on September 27; however, they lost to the Tampa Bay Rays in that game 5–1. The 2019 season was the final season the team shared the Coliseum with the Oakland Raiders. The Raiders relocated to Las Vegas prior to the following season leaving the Coliseum as a baseball-only facility for the first time since 1994.
