The Mountain Region is one of ten United States regions that currently send teams to the Little League World Series, the largest youth baseball competition in the world. The region was created in 2022 when the LLWS was expanded from 16 teams (eight U.S. teams and eight "International" teams from the rest of the world) to 20 teams (ten U.S. and ten International).
The Mountain Region is made up of five states.
