The 1937 Philadelphia Athletics season involved the A's finishing seventh in the American League with a record of 54 wins and 97 losses.

Offseason

On January 11, 1937, at the club's annual meeting, John Shibe officially retired from the day-to-day operations of the Athletics, although he had not been with the team since August 1936. Connie Mack, the team's other principal owner, was elected club president. Shibe died on July 11, leaving Mack as sole owner of the team.

Regular season

The Athletics had refused the American League's directives to add numbers to all player uniforms, and would not post visiting players' uniform numbers on the scoreboard. The team argued that they posted both teams' full lineups to the scoreboard, then the only ballpark to do so, making numbers superfluous. The team relented to its fans who wished to be able to identify pitchers warming up in the bullpens, and players during pregame practice. The club started to use uniform numbers during the 1937 season. They were the last team in the American League to do so. The Athletics set a Major League record which still stands for the fewest batters hit by a pitch in a season, with only 5.
