Each year, Little League® provides its constituent leagues with current Little League rules, regulations, and policies that outline and define the operation of the program. It is important for all Little League volunteers and parents to be familiar with the most up-to-date version of Little League’s Official Regulations, Playing Rules, and Operating Policies. These rulebooks, published for all divisions of Little League Baseball®, Little League Softball®, and the Little League Challenger Division® provide the structure and support for local leagues and Districts to provide a meaningful Little League experience for all children in their community.
Little League® International has assembled an online resource page dedicated to baseball bat information, that includes the latest bat information, current Little League Baseball® rules and regulations governing bats, and a series of frequently asked questions.
The Little League® Rulebook App has been updated for the 2021 season. Please review the significant updates, as well as all the additional rule and regulation updates for Little League® Baseball, Softball, and Challenger within the Rulebook App.
