Description: Detailed large political map of Louisiana State, showing cities, towns, parishes, roads highway, US highways and State routes.
Map of Louisiana - Louisiana with cities, counties, and roads network. Note on terms: Louisiana uses parishes rather than counties. To match the search language and the labels on our map, we use parishes (counties) together. Seats are the official parish seats.
This Map of Louisiana is a detailed map focused on a parish grid, parish seats, nearby cities and towns, and thin, road-light corridor lines so you can place locations without turning the graphic into a driving atlas. It is exactly the Louisiana map with cities, counties and roads network people look for when they need parish context first. Counties are color-blocked by parish, county seats are marked, borders with Texas, Arkansas, and Mississippi are clean, and the Gulf of Mexico coast is drawn with bays, sounds, and the Mississippi delta marshes. Interstates like I-10, I-12, I-20, I-49, and I-55 appear only as orientation threads, keeping the visual focus on parishes and seats. That balance makes this layout one of the best map styles for residents, travelers, teachers, and geography students.
Start by framing Louisiana on the page. The Sabine River marks most of the Texas line, the Red River cuts diagonally through the state, and the Mississippi River forms nearly all of the east border with Mississippi before fanning into the grand delta south of New Orleans. Lakes and bays jump out on our map: Toledo Bend Reservoir on the Sabine, Calcasieu Lake, Vermilion Bay, Atchafalaya Bay, Lake Pontchartrain, Lake Maurepas, Barataria Bay, Breton Sound, Terrebonne Bay, and the open Gulf of Mexico.
In the corner where Arkansas, Louisiana, and Texas meet, the map highlights Caddo Parish with Shreveport as the city hub and the parish seat at Shreveport. Just east is Bossier Parish with seat Benton and the city of Bossier City opposite Shreveport. Southward, De Soto Parish centers on Mansfield along a light north–south road cue. West of Caddo, hugging Texas, sits Sabine Parish with Many as the seat near Toledo Bend. East of Bossier is Webster Parish with seat Minden. North toward Arkansas lie Claiborne (seat Homer) and Union (seat Farmerville). Along the Red River valley the map puts Red River Parish with seat Coushatta, then Natchitoches Parish with the city and seat Natchitoches clearly labeled on the river bluffs.
The Red River swings east across Grant Parish with seat Colfax and into Rapides Parish where Alexandria anchors the center of the state. North of the Ouachita corridor the delta parishes step east to the Mississippi: Bienville (seat Arcadia), Jackson (seat Jonesboro), Lincoln (seat Ruston), Ouachita (seat Monroe, with West Monroe shown), Morehouse (seat Bastrop), Richland (seat Rayville), West Carroll (seat Oak Grove), East Carroll (seat Lake Providence), Madison (seat Tallulah), Tensas (seat St. Joseph), Concordia (seat Vidalia facing Natchez), and Catahoula (seat Harrisonburg at a river bend). South of Monroe sits Caldwell Parish with Columbia as seat, then La Salle Parish with Jena. The light ribbon of I-20 across Shreveport, Minden, Ruston, Monroe, and Tallulah is purposely thin, simply giving you bearings as you scan parishes.
The heart of the map is the Crossroads region. Rapides Parish marks Alexandria as a bold anchor, with Pineville just across the river. West of Rapides, Vernon Parish lists Leesville; south of Vernon, Beauregard Parish lists DeRidder. Between the Red and Atchafalaya systems, Avoyelles Parish shows seat Marksville surrounded by a lattice of bayous; Evangeline Parish lists Ville Platte; and St. Landry Parish lists the historic seat Opelousas with Eunice nearby. South-central Allen Parish lists Oberlin; eastward, St. Martin Parish lists St. Martinville and Breaux Bridge at the Atchafalaya edge. The Crossroads is where I-49 makes a simple north–south cue between Shreveport, Natchitoches, Alexandria, and Lafayette without crowding parish names.
Slide southwest to the prairies and the bay coast. Calcasieu Parish puts Lake Charles on Calcasieu Lake; Cameron Parish stretches along the Gulf with seat Cameron at the mouth of the Calcasieu ship channel. East of Calcasieu, Jefferson Davis Parish lists Jennings; Acadia Parish lists Crowley; Vermilion Parish lists Abbeville on the Vermilion River; Lafayette Parish centers on Lafayette, a bold label on our map because of its regional role. South of Lafayette, Iberia Parish lists New Iberia and the port of Avery Island area nearby; St. Mary Parish lists Franklin and the coastal cities Morgan City and Berwick along the Atchafalaya outlets. Eastward the map shows Terrebonne Parish with Houma, Lafourche Parish with Thibodaux and Port Fourchon on the narrow Gulf rim. This belt includes US-90 as a light orientation line from Lake Charles to New Orleans, but the parish colors and seats stay central.
Follow the Mississippi upstream and you step through the famous River Parishes. St. Charles Parish lists Hahnville; St. John the Baptist Parish lists Edgard with population center LaPlace labeled; St. James Parish lists Convent with Lutcher and Gramercy; Ascension Parish lists historic seat Donaldsonville with Gonzales marked along the I-10 cue. On the east bank toward the Gulf, Plaquemines Parish extends down the delta with seat Pointe à la Hache and the developed center at Belle Chasse clearly marked. St. Bernard Parish lists Chalmette. Inside the crescent, Orleans Parish is the consolidated city-parish of New Orleans, with lakefront and delta outlets drawn in detailed blue marsh textures. North of Lake Pontchartrain the map shows the Northshore: St. Tammany Parish with seat Covington and cities Slidell and Mandeville spaced along the lake, Washington Parish with Franklinton, and Tangipahoa Parish with Amite City and the city Hammond on the I-12 cue.
Back up the river from New Orleans sits East Baton Rouge Parish with Baton Rouge as parish seat and state capital. Across the Mississippi lies West Baton Rouge Parish with Port Allen. North of Baton Rouge the topography rises into the Felicianas where West Feliciana Parish lists St. Francisville and East Feliciana Parish lists Clinton. West of the river bend the map places Pointe Coupee Parish with New Roads on False River; south across the Atchafalaya is Iberville Parish with Plaquemine; further west is St. Martin already noted. The road-light treatment of I-10 and US-190 keeps the parish blocks readable while giving you quick bearings through Louisiana’s political heartland.
East of Baton Rouge and north of Lake Pontchartrain, the Florida Parishes run to Mississippi. From west to east they are East Baton Rouge, Livingston (seat Livingston), Tangipahoa (seat Amite City), Washington (seat Franklinton), and St. Tammany (seat Covington). The Pearl River and Stennis area on the state line are shown to place the border context with Mississippi and the Gulf Coast cities.
A parish map answers questions that 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 see that is Jefferson Parish adjacent to Orleans. If a student wants to know which parishes touch Lake Pontchartrain, the colored blocks make it obvious: Jefferson, Orleans, St. Charles, St. John the Baptist, St. Tammany, Tangipahoa, Livingston, and St. Bernard by marsh. If a traveler needs to place Alexandria relative to Lafayette, the light cue of I-49 helps, yet parish names and seats stay uncluttered. That is why this detailed map works so well: parish identity first, gentle roads network second.
Use this index with the map open. Each line lists the parish, its seat, and one or two labeled cities or water cues for orientation. I retain Louisiana’s parish names but keep “county” in the SEO text above.

Louisiana has 64 parishes, and this map shows every parish as a colored block with its parish seat.
People often search "counties" for Louisiana. We honor that query while consistently labeling parishes and parish seats on the map.
