Port Sulphur is a town in Plaquemines Parish, in the southeastern part of the U.S. state of Louisiana. It is situated on the west bank of the Mississippi River near the mouth of the river, approximately 45 miles (72 km) southeast of New Orleans.
Geography
Port Sulphur lies at coordinates 29°31′N 89°32′W and has a total area of 1.38 square miles (3.57 km²), of which 1.32 square miles (3.42 km²) is land and 0.06 square miles (0.15 km²) is water, according to the United States Census Bureau. The town is located within the Mississippi River Delta region and is protected by levees and floodwalls.
History
The community developed in the early 20th century around the sulfur mining and processing operations established by the American Sulphur Company. The name “Port Sulphur” reflects this industrial origin. The town’s growth was closely tied to the sulfur industry, which declined after World II. In 1965, the area was heavily damaged by Hurricane Betsy, and in 2005 it suffered extensive flooding and wind damage during Hurricane Katrina. Reconstruction efforts in the subsequent years focused on rebuilding homes, public infrastructure, and restoring the local economy.
Demographics
According to the 2020 United States Census, Port Sulphur had a population of 1,507 residents. The racial and ethnic composition was predominantly non‑Hispanic White, with significant African American and Hispanic/Latino minorities. The median household income was below the state average, and a notable proportion of the population lived below the federal poverty line, reflecting the socioeconomic challenges typical of many post‑hurricane recovery communities in the region.
Economy
The local economy historically centered on sulfur extraction, but today it is characterized by a mix of small businesses, services related to the maritime industry, and employment in nearby industrial facilities, including shipyards and petroleum processing plants. Commercial fishing and tourism, particularly for fishing and recreational boating, also contribute to the town’s economic activity.
Education
Port Sulphur is served by the Plaquemines Parish School Board. The primary public school for the community is Port Sulphur Elementary School, which provides education from pre‑kindergarten through eighth grade. High school students typically attend Plaquemines High School in neighboring Port Sulphur or other parish schools, depending on zoning and transportation availability.
Infrastructure
Transportation access to Port Sulphur includes Louisiana Highway 23, which connects the town to the Greater New Orleans area and other local communities along the Mississippi River’s west bank. The town is also served by levee systems managed by the U.S. Army Corps of Engineers, which provide flood protection. Utility services are provided by regional entities, and the town maintains its own police department and volunteer fire department.
