Roughly two-fifths of the parish is water, including Lake Pontchartrain frontage, Lake Maurepas wetlands, and the Bonnet Carr\u00e9 Spillway, which diverts Mississippi floodwater into the lake. The parish borders <a href=\"https:\/\/townsvillages.com\/us\/tangipahoa-parish\/\">Tangipahoa Parish<\/a> to the north, <a href=\"https:\/\/townsvillages.com\/us\/saint-charles-parish\/\">St. Charles Parish<\/a> to the east, Lafourche Parish to the south, <a href=\"https:\/\/townsvillages.com\/us\/saint-james-parish\/\">St. James Parish<\/a> to the west, and <a href=\"https:\/\/townsvillages.com\/us\/ascension-parish\/\">Ascension Parish<\/a> and <a href=\"https:\/\/townsvillages.com\/us\/livingston-parish\/\">Livingston Parish<\/a> to the northwest.<\/p>\n<h2>Demographics<\/h2>\n<p>St. John the Baptist Parish had 42,477 residents at the 2020 census. LaPlace, the largest community, and Reserve are the two population centers; together they hold most of the parish&#8217;s residents. Median household income in the parish runs well below the Louisiana median of $58,229. Population density is roughly 200 people per square mile of land.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>The river corridor through the parish carries some of Louisiana&#8217;s largest chemical and petroleum-refining plants, a legacy of the sugar-plantation economy that industrialized through the 20th century. Marathon Petroleum operates a major refinery in Garyville, and several other chemical facilities line the east and west banks. Away from the industrial corridor, the parish&#8217;s National Historic Landmark plantations &mdash; Evergreen, Whitney, and San Francisco &mdash; draw visitors interested in Louisiana&#8217;s plantation and slavery history, and Whitney Plantation operates as a museum focused on the lives of the enslaved.<\/p>\n<h2>History<\/h2>\n<p>St. John the Baptist Parish was created in 1807 as one of the original 19 parishes of the Territory of Orleans, taking its name from the St. John the Baptist Catholic Church built on the site in 1772. German Catholic immigrants settled the area in the early 1720s, making it one of the earliest permanent European settlements in Louisiana after Natchitoches and New Orleans. In 1811 the parish was the site of the German Coast Uprising, the largest slave insurrection in United States history, when several hundred enslaved people marched toward New Orleans before being suppressed.<\/p>\n<h2>Getting There<\/h2>\n<p>Interstate 10 crosses the parish&#8217;s east bank near LaPlace, with Interstate 55 running north out of the same interchange; US Highway 61 and US Highway 51 also cross the parish, and Louisiana Highway 18 (River Road) follows the Mississippi through the west-bank communities.<\/p>\n<ul>\n<li>New Orleans &mdash; 25 miles southeast<\/li>\n<li>Baton Rouge &mdash; 45 miles northwest<\/li>\n<li>Hammond &mdash; 25 miles north<\/li>\n<li>Houma &mdash; 35 miles south<\/li>\n<\/ul>\n<p>Louis Armstrong New Orleans International Airport, about 15 miles east of LaPlace, is the nearest commercial airport.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Where is St. John the Baptist Parish?<\/strong><br \/>It is in southeast Louisiana, on both banks of the Mississippi River between Baton Rouge and New Orleans, part of the New Orleans&ndash;Metairie metro area.<\/p>\n<p><strong>What is the population of St. John the Baptist Parish?<\/strong><br \/>42,477 at the 2020 census.<\/p>\n<p><strong>How big is St. John the Baptist Parish?<\/strong><br \/>348 square miles total, 213 square miles of land and 135 square miles of water.<\/p>\n<p><strong>What is the parish seat?<\/strong><br \/>Edgard, an unincorporated community on the river&#8217;s west bank.<\/p>\n<p><strong>How many towns are in St. John the Baptist Parish?<\/strong><br \/>None are incorporated; the parish has six census-designated places (LaPlace, Reserve, Garyville, Edgard, Wallace, and Pleasure Bend) plus a number of smaller unincorporated communities.<\/p>\n<p><strong>What ZIP codes are in St. John the Baptist Parish?<\/strong><br \/>70068 (LaPlace), 70084 (Reserve), 70051 (Garyville), and 70049 (Edgard, Wallace, and Mount Airy).<\/p>\n<p><strong>What is St. John the Baptist Parish known for?<\/strong><br \/>Its Mississippi River petrochemical corridor and its cluster of preserved antebellum plantations, including Whitney Plantation&#8217;s museum on slavery.<\/p>\n<p>More counties in this state: <a href=\"https:\/\/townsvillages.com\/us\/category\/louisiana\/\">Towns and villages in Louisiana<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>St. John the Baptist Parish is a parish in Louisiana, United States, on the east and west banks of the Mississippi River between Baton Rouge and New Orleans.
