Welcome to the Mount Joy Athletic Association

The MJAA is a youth recreational baseball organization serving the Northwest region of Lancaster County.  For 50 years, we have focused on player development and teaching the strategies of the game that has led to championship teams, numerous professional baseball players, and multiple connections to the Major Leagues, including the Hall of Fame.  For generations, we have lead young boys down the path to success on and off the field.  We invite you to come be a part of our success, and write the baseball history of tomorrow.

The greatest of all, the game which seems to breathe the restless spirit of American life, that calls for quick action and quicker thinking, that seems characteristic of a great nation itself, is baseball.
- Charles M. Conlon, 1913
