Little League Baseball formed the Southwestern Region in 2002. Arkansas, Louisiana, Mississippi, Oklahoma, and Texas (both Texas East and Texas West) previously competed in the Southern (1957-2000) and Gulf States (2001) regions. Colorado and New Mexico were moved from the Western Region, where they competed in the Northwest and West Regions.
