Major League Baseball Players Association

The Major League Baseball Players Association (MLBPA) is the labor union representing all current Major League Baseball (MLB) and Minor League Baseball (MiLB) players. All players, managers, coaches, and athletic trainers who hold or have held a signed contract with a Major League club are eligible for membership in the Association. The MLBPA has three major divisions: a labor union, a business (Players Choice Group Licensing Program), and a charitable foundation (Major League Baseball Players Trust).

On August 28, 2022, the MLBPA publicly launched a campaign to help MiLB players unionize. On September 9, 2022, MLB voluntarily recognized the MLBPA as the union for over 5,500 MiLB players playing rookie level to Triple-A.
