St. John the Baptist Parish


St. John the Baptist Parish is located in the heart of Louisiana’s sugarcane industry between Baton Rouge and New Orleans. Two major interstate highways (I-10 and I-55), four main-line railroads, close proximity to Louis Armstrong New Orleans International Airport and the St. John the Baptist Parish General Aviation Airport, and the Globalplex Intermodal Terminal comprise St. John the Baptist Parish’s superior transportation infrastructure, which opens industry to North America and the world.


St. John the Baptist Parish offers a high quality of life, a strong sense of community and ample recreational activities. Residents enjoy top notch hunting and fishing, golf, superb dining, frequent festivals and special events. The parish’s festive spirit is perhaps no more evident than on Christmas Eve each year, when residents ignite their traditional bonfires along the Mississippi River levee.
