The Gulf States League was a Class A American minor baseball league that existed for one season — 1976 — and was based in the American states of Texas and Louisiana. Although its teams were not affiliated with any Major League Baseball farm systems, the GSL was an "official" minor circuit and a member of the National Association of Professional Baseball Leagues. Established before the boom in minor and independent league baseball attendance that began in the 1980s, the Gulf States League did not survive after its maiden season. Instead, the league reorganized without any teams in Louisiana, and was renamed the Lone Star League for 1977.
