Overview

Iberville Parish is a local government unit in southeastern the state of Louisiana, lying just south of Baton Rouge along the Mississippi River. The parish seat is Plaquemine, a small city with historic buildings and civic institutions. The parish is one of Louisiana's civil divisions commonly called a parish rather than a county, and its name reflects the area's French roots—its French name is noted as Paroisse d'Iberville.

Geography and communities

The parish occupies low-lying riverine and wetlands terrain characteristic of the lower Mississippi floodplain. Levees, bayous and marshes shape local land use and transportation. Principal towns and communities include:

  • Plaquemine (parish seat)
  • St. Gabriel
  • White Castle

History

Iberville Parish was established in 1807 during the early organization of the Territory of Orleans. Its settlement and cultural development were heavily influenced by French and Spanish colonial eras, plantation agriculture and the Mississippi River as a transportation corridor. The parish name honors the French explorer and colonial leader associated with early Louisiana history.

Economy and culture

Local economic activity combines agriculture—most notably sugar cane and other crops suited to the river plain—with industrial and petrochemical operations located along the river corridor. Communities retain strong French-Creole traditions visible in place names, local cuisine, and festivals. Regional connections with the Baton Rouge metropolitan area influence employment and services.

Demographics and administration

According to the 2010 census, Iberville Parish had a population of 33,387. The parish government is centered in Plaquemine and provides typical local services such as courts, law enforcement, and infrastructure management. Flood control and coastal-wetland conservation are ongoing concerns for residents and planners.

Notable facts

The parish combines rural and small-town character with historical sites tied to Louisiana's colonial and agricultural past. Its riverside setting has shaped its economy, risks and cultural life, making Iberville Parish a distinct part of the broader Mississippi River and Gulf Coast region.
