Iberville Parish () is a parish located south of Baton Rouge in the U.S. state of Louisiana, formed in 1807. The parish seat is Plaquemine. The population was 30,241 at the 2020 census.

History The parish is named for Pierre Le Moyne d'Iberville, who founded the French colony of Louisiana.

A few archaeological efforts have been made in the parish, mainly to excavate the Native American burial mounds that have been identified there. The first expedition, led by Clarence B. Moore, was an attempt at collecting data from a couple of the sites, and it set the groundwork for later projects. Moore was mainly interested in the skeletal remains of the previous inhabitants, rather than excavating for archaeological items. Archaeologists are especially interested in these sites because of their uniformity and size. Some of the mounds are seven hundred feet long, a hundred feet wide and six feet tall. Most of them contain human remains.Ford, James A: "Measuring the Flow of Time", page 415. The University of Alabama Press, 1999
