Iberville Parish, Louisiana

Iberville Parish is a place where Louisiana history and natural beauty come together. Located just across the Mississippi River from Baton Rouge, it offers an easy connection to the state capital while maintaining a distinctly rural character.

The parish is named after Pierre Le Moyne d’Iberville, the French-Canadian explorer associated with the early French settlement of Louisiana. The Atchafalaya Basin, one of the largest river swamps in the United States, forms much of the parish’s western landscape and provides a rich habitat for wildlife.

The parish features a mix of small towns, rural communities, and wetlands, including Plaquemine, the parish seat, and St. Gabriel. The waterways and forests of Iberville Parish provide excellent opportunities for fishing, hunting, boating, and airboat tours, making it a popular destination for outdoor enthusiasts.
