The Louisiana Border refers to the boundaries that define the state of Louisiana in the United States. It is bordered by Texas to the west, Arkansas to the north, and Mississippi to the east. To the south, it has a coastline along the Gulf of Mexico, which plays a significant role in the state's economy and culture. The border with Texas is particularly notable, as it is one of the longest state borders in the U.S. The Sabine River serves as a natural boundary between Louisiana and Texas. Additionally, the Mississippi River forms part of the border with Mississippi, contributing to the region's rich history and geography.
