In Major League Baseball, the Manager of the Year Award is an honor given annually since 1983 to two outstanding managers, one each in the American League (AL) and the National League (NL). The winner is voted on by 30 members of the Baseball Writers' Association of America (BBWAA). Each submits a vote for first, second, and third place among the managers of each league.[a] The manager with the highest score in each league wins the award.

In baseball, the field manager is the equivalent of a head coach who is responsible for overseeing and making final decisions on all aspects of on-field team strategy, lineup selection, training and instruction. Managers are typically assisted by a staff of assistant coaches whose responsibilities are specialized. Field managers are typically not involved in off-field personnel decisions or long-term club planning, responsibilities that are instead held by a team's general manager.
