The Junior League Baseball Division is a program for boys and girls ages 13-14 (8th grade), using a conventional 90-foot diamond with a pitching distance of 60 feet, 6 inches. Modified diamond dimensions may be used during the regular season.

The local league has an option to choose a Tournament Team (or "All Stars") of 12-14-year-olds from within this division (and/or from within the Senior League Division), and the team may enter the International Tournament.

The culmination of the International Tournament is the Junior League Baseball World Series, featuring teams from around the world. All expenses for the teams advancing to the World Series (travel, meals and housing) are paid by Little League International.

Parents are strongly encouraged to become involved in this teenage division of Little League. After completing a Little League volunteer application and passing a required national background check, parents may become involved in practices, and be eligible as coaches, managers, umpires, local league board members and other volunteer positions within the league.
