Description: Detailed large map of Louisiana State, USA showing cities, towns, parish formations, roads highway, US highways and State routes.
This map of Louisiana with cities, parishes, and towns is already large enough to read directly on your desktop. To see a full-screen zoom view on a phone or tablet, tap the map image (or tap the Zoom Map label above the image). Scan by shading by parish first, meaning the 64 parishes are in various colored blocks with each parish's seat in bold. Use the interstate system and the Mississippi, Red, and Sabine rivers for quick orientation. Note that the light road layer is intentionally minimal and not designed for turn-by-turn directions using interstate (I-10, I-20, I-49). If you want a specific city or parish, the full parish and seat index and FAQ's lower on this page are the quickest route to click straight to it.
Map of Louisiana (USA). Louisiana map with cities, parishes, and towns. Use this detailed map to understand Louisiana’s full parish grid, every administrative capital (parish seat), the major cities and towns, bordering states and waters, and a few highway cues for orientation only. It is the best map style for residents, travelers, and geography students who want clarity without road clutter.
Borders and waters at a glance: Louisiana borders Texas across the Sabine River to the west, Arkansas along a surveyed line to the north, and Mississippi along the historic 31st parallel and the Mississippi River to the east, with the Gulf of Mexico framing the entire south coast. All 64 parishes are shown, and the Mississippi, Red, Atchafalaya, and Ouachita rivers act as the main orientation lines running through the interior. Light corridor cues for I-10, I-12, I-20, I-49, and I-55 help place the state's biggest anchors the cartography marks clearly: New Orleans in Orleans Parish, Baton Rouge in East Baton Rouge Parish, Shreveport in Caddo Parish, and Lafayette in Lafayette Parish.
Start in the corner where Arkansas, Louisiana, and Texas come together. Caddo Parish anchors the corner with Shreveport serving as both the city hub and the parish seat on the Red River. Just east, Bossier Parish lists Benton as its seat, with Bossier City filling in as the twin-city anchor across the river from Shreveport. South of Caddo, De Soto Parish centers on Mansfield along a quiet north-south road cue, and west along the Texas line, Sabine Parish keeps Many as its seat near the Toledo Bend shoreline. Red River Parish, seat Coushatta, and Natchitoches Parish, seat and city both Natchitoches, carry the Red River valley southeast along its bluffs. East of Bossier, Webster Parish lists Minden as seat, while Claiborne Parish (Homer) and Union Parish (Farmerville) sit toward the Arkansas line, the latter near Lake D'Arbonne. Bienville Parish, seat Arcadia, sits between them, and south of Bienville, Lincoln Parish holds the university city of Ruston as its seat, with Jackson Parish just below it at Jonesboro. Together these twelve parishes frame the pine-hill country north and west of Louisiana's Red River corridor.
East of the pine hills, the map steps down into the Ouachita and delta parishes on the way to the Mississippi River. Ouachita Parish, seat Monroe (with West Monroe also labeled), sits at the Ouachita River crossing. Morehouse Parish lists Bastrop just north of Monroe, and Richland Parish lists Rayville just east. Continuing toward the river, West Carroll Parish (Oak Grove) and East Carroll Parish (Lake Providence) sit side by side on the state's northeast corner, with Madison Parish (Tallulah) just south along the I-20 approach to Vicksburg. Tensas Parish keeps St. Joseph as its seat on a wide river bend, and Concordia Parish lists Vidalia directly across the water from Natchez, Mississippi. West of the river, Catahoula Parish centers on Harrisonburg at a triangle of the Ouachita and Black rivers, with Caldwell Parish (Columbia) just north of it. Franklin Parish, seat Winnsboro, sits between Rayville and the delta fields, while La Salle Parish (Jena) and Winn Parish (Winnfield) fill the pine uplands to the west, rounding out this thirteen-parish stretch bridging the hills and the river.
The heart of the map is the Crossroads region, where Rapides Parish marks Alexandria as a bold anchor on the Red River, with Pineville labeled just across the water. Grant Parish, seat Colfax, sits between Alexandria and Natchitoches along the river's bend. West of Rapides, Vernon Parish lists Leesville as its seat, and it is Louisiana's largest parish by land area. Just south, Beauregard Parish lists DeRidder toward the Texas pine belt. South of Rapides, Allen Parish keeps Oberlin as its seat on the prairie edge, and Evangeline Parish lists Ville Platte in rice and crawfish country. Between the Red and Atchafalaya systems, Avoyelles Parish shows seat Marksville surrounded by a lattice of bayous, and St. Landry Parish lists the historic seat Opelousas with Eunice labeled to the west. This eight-parish cluster is where I-49 makes a simple north-south cue linking Shreveport, Natchitoches, Alexandria, and Lafayette without crowding the parish names.
Slide southwest to the prairies and the bay coast. Calcasieu Parish puts Lake Charles on Calcasieu Lake, while Cameron Parish stretches the longest Gulf shoreline in the state with seat Cameron near the mouth of the ship channel. East of Calcasieu, Jefferson Davis Parish lists Jennings, Acadia Parish lists Crowley, and Vermilion Parish lists Abbeville on the Vermilion River near Vermilion Bay. Lafayette Parish centers on the city of Lafayette, a bold label on the map as Acadiana's cultural hub. South of Lafayette, Iberia Parish lists New Iberia near the Avery Island area, and St. Martin Parish lists St. Martinville, with Breaux Bridge shown at the Atchafalaya edge. St. Mary Parish lists Franklin as seat, with the coastal cities Morgan City and Berwick marked at the Atchafalaya outlet. Terrebonne Parish shows Houma, and Lafourche Parish shows Thibodaux, both stretching south along narrow bayou ridges toward Port Fourchon and the Gulf rim. Assumption Parish, seat Napoleonville, sits between the Atchafalaya and Mississippi systems, closing out this twelve-parish coastal sweep.
Follow the Mississippi downstream from Baton Rouge and you step through the famous River Parishes. St. Charles Parish lists Hahnville, St. John the Baptist Parish lists Edgard with the population center LaPlace labeled nearby, and St. James Parish lists Convent, with Lutcher and Gramercy also shown. Ascension Parish keeps the historic seat Donaldsonville, with Gonzales marked along the I-10 cue. On the east bank toward the Gulf, Plaquemines Parish extends far down the delta with seat Pointe a la Hache and the developed center at Belle Chasse clearly marked, while St. Bernard Parish lists Chalmette just east of the city. Inside the crescent, Orleans Parish is the consolidated city-parish of New Orleans, with lakefront and delta outlets drawn in detailed marsh textures, and Jefferson Parish wraps around it with seat Gretna and the cities Metairie and Kenner marked north of the river. These eight parishes carry most of Louisiana's population within a short drive of the Mississippi's final bends.
Back upriver from New Orleans sits East Baton Rouge Parish, with Baton Rouge as both parish seat and state capital. Across the Mississippi, West Baton Rouge Parish lists Port Allen, and it is Louisiana's smallest parish by land area. North of the capital the land rises gently into the Felicianas, where West Feliciana Parish lists St. Francisville on the river bluffs and East Feliciana Parish lists Clinton. West of the river bend, Pointe Coupee Parish lists New Roads on the False River oxbow, and just south, Iberville Parish lists Plaquemine. These six parishes anchor Louisiana's political heartland, with I-10 and US-190 keeping the parish blocks readable while giving quick bearings through the region.
East of Baton Rouge and north of Lake Pontchartrain, the Florida Parishes run to the Mississippi state line. St. Tammany Parish lists Covington as seat, with Slidell and Mandeville marked along the lake. Tangipahoa Parish lists Amite City as seat, with the city of Hammond shown on the I-12 cue. Livingston Parish keeps its own name, Livingston, as the seat, with Denham Springs marked toward Baton Rouge. Washington Parish lists Franklinton, with Bogalusa labeled near the Pearl River, and St. Helena Parish, the quietest of the five, lists Greensburg as its seat in the piney interior between Livingston and the Mississippi line. Together these five parishes close out the parish grid on Louisiana's eastern edge.
A parish map answers questions a turn-by-turn sheet cannot. If you live in Monroe, this map tells you immediately that you are in Ouachita Parish. If you work near Kenner and Metairie, you can see that is Jefferson Parish, right next to Orleans. If a student wants to know which parishes ring Lake Pontchartrain, the colored blocks make it obvious: Jefferson, Orleans, St. Tammany, Tangipahoa, Livingston, St. John the Baptist, and St. Charles. If a traveler needs to place Alexandria relative to Lafayette, the light cue of I-49 helps, while parish names and seats stay uncluttered. That is why this detailed map works so well: parish identity first, gentle roads network second.
Four rivers do most of the orientation work on this page. The Mississippi River traces the northeast corner, forms much of the eastern state line, and curves past Baton Rouge and New Orleans on its way to the delta. The Red River cuts diagonally from the Texas-Arkansas corner through Natchitoches and Alexandria before feeding the Atchafalaya system. The Atchafalaya River drains the basin between Lafayette and Baton Rouge, out to Morgan City and the Gulf. The Ouachita River threads the northeast parishes past Monroe on its way south. Keep these four in mind and any parish on the map is easy to place.
Road-light orientation: The road layer is intentionally minimal. I-10 runs Lake Charles-Lafayette-Baton Rouge-New Orleans. I-12 bypasses New Orleans to the north through Hammond and Slidell. I-20 runs Shreveport-Minden-Ruston-Monroe-Tallulah. I-49 links Shreveport-Natchitoches-Alexandria-Lafayette. I-55 clips the southeast corner near Hammond on its way to Mississippi. None of these are meant for turn-by-turn navigation, only as parish-placement cues.

Louisiana borders Texas across the Sabine River to the west, Arkansas along a surveyed line to the north, and Mississippi along the historic 31st parallel and the Mississippi River to the east, with the Gulf of Mexico framing the entire southern coast. The state holds 64 parishes, more subdivisions than all but a handful of states. Vernon Parish is the largest by land area at roughly 1,328 square miles, while West Baton Rouge Parish is the smallest at roughly 204 square miles. East Baton Rouge Parish, home to the capital, is the most populous parish at roughly 453,000 residents, while Tensas Parish is the least populous at roughly 3,800. Louisiana's original 19 parishes, including Orleans, Natchitoches, Rapides, Iberville, Pointe Coupee, Ouachita, and Concordia, were all carved out on March 31, 1807, so no single parish holds the oldest title alone. Louisiana covers about 52,378 square miles in total, with about 43,204 square miles of land. The capital, Baton Rouge, sits in East Baton Rouge Parish on the Mississippi River, and the state's major metros run from New Orleans and Baton Rouge through Shreveport-Bossier City and Lafayette to Lake Charles. Landscape-wise, the state moves from piney uplands in the north and west, through the Red River and Ouachita valleys, into the Atchafalaya Basin's wetlands, and out to the coastal marshes, bayous, and barrier islands along the Gulf.
Louisiana's ten largest cities by current population are New Orleans (about 362,700, Orleans Parish), Baton Rouge (about 222,800, East Baton Rouge Parish), Shreveport (about 175,900, Caddo Parish), Metairie (about 139,100, Jefferson Parish), Lafayette (about 123,300, Lafayette Parish), Lake Charles (about 82,700, Calcasieu Parish), Kenner (about 65,100, Jefferson Parish), Bossier City (about 63,300, Bossier Parish), Monroe (about 46,900, Ouachita Parish), and Alexandria (about 42,900, Rapides Parish). New Orleans anchors tourism, the Port of New Orleans, and healthcare, while Baton Rouge centers state government, LSU, and a major petrochemical corridor along the Mississippi. Lafayette drives Acadiana's energy-services and Cajun-food economy, and Lake Charles hosts one of the busiest LNG export hubs on the Gulf Coast alongside its ship channel. Shreveport-Bossier City anchors the northwest with a growing film and healthcare presence. Agriculture still shapes the state's identity too: rice and crawfish farming spread across Acadiana's prairies, sugarcane lines the River Parishes, and soybeans and cotton dominate the northeast delta. With hundreds of miles of navigable Mississippi River frontage and several deepwater ports, Louisiana moves more waterborne cargo than almost any other state.
Louisiana's cultural identity runs through its parishes as much as its cities. Cajun and Creole heritage centers on Acadiana, in parishes like Lafayette, St. Martin, and Iberia, where French language, zydeco and Cajun music, and dishes like gumbo and boudin trace back to Acadian exiles who settled the bayou country in the 1700s. Mardi Gras reaches its peak in Orleans Parish's French Quarter, but parishes across the south, including St. Landry and Lafourche, hold their own Carnival traditions. New Orleans, in Orleans Parish, is widely credited as the birthplace of jazz, and the city's music clubs still carry that legacy forward. Historic sites include the Poverty Point earthworks, a UNESCO World Heritage site in West Carroll Parish, and the riverside bluffs of West Feliciana Parish. Higher education is spread across the parishes too, with LSU in East Baton Rouge Parish, Tulane and Loyola in Orleans Parish, the University of Louisiana at Lafayette in Lafayette Parish, and Louisiana Tech in Lincoln Parish.
On this map, Driskill Mountain (Bienville Parish) and the Mississippi, Red, and Atchafalaya rivers double as landmarks for finding parishes quickly. For elevation, terrain, watersheds, and land-cover detail, see our Physical Map of Louisiana.
Louisiana has a humid subtropical climate with hot, humid summers and mild winters, plus a hurricane season that runs June through November along the Gulf Coast. For a full seasonal and biome breakdown, see our Physical Map of Louisiana.
North-south travel runs mainly on I-49 (Shreveport to Lafayette through Natchitoches and Alexandria) and I-55 (a short southeast-corner run toward Mississippi). East-west travel runs on I-10 (Lake Charles to Lafayette to Baton Rouge to New Orleans) and I-20 (Shreveport to Monroe to the Mississippi line), with I-12 bypassing New Orleans to the north through Hammond and Slidell. Keep in mind that ZIP codes do not follow parish lines in Louisiana, so a single ZIP code can span two parishes. Always confirm the parish name directly from the map or index rather than assuming it from a ZIP prefix.
Use this as a quick index. Every line lists the parish with its parish seat (and a familiar city when the map labels one). Short cues mention river, border, or gentle corridor context only.
