Louisiana county geography overview

Louisiana has 64 parishes, which places it 24th among the 50 state and District of Columbia maps in this atlas when ordered by number of county-level units. Their combined 43,215.1 square miles of land place the state 33rd by mapped land area.

The average county-level area is 675 square miles, while the median is 646 square miles. The median is often the better description of a typical unit because one or two very large areas can pull the average upward. The five largest units together account for about 15% of the state’s mapped land area.

Rankings use land area rather than total area. This avoids making coastal or lake counties appear larger solely because their boundaries include extensive water.

Alphabetical list of Louisiana parishes

The table is alphabetical, so it works as a name and FIPS-code reference rather than an area ranking. Every identifier begins with the Louisiana state FIPS prefix 22. Land and water figures are rounded to one decimal place.

How to read and use this map

County lines are administrative boundaries, not postal routes. A mailing address can use a city name associated with a neighboring area, and ZIP codes can cross county lines. When you need to identify a county for an address, confirm it with an official geocoder or local government source.

For classroom or planning use, download a PDF from the controls above. Labelled exports use numbered callouts for crowded areas; numbered quiz maps match the alphabetical county list. SVG files keep the boundary lines sharp at larger paper sizes.

Interpreting the water figure: About 17% of the summed mapped area in this state is water. County water area can include coastal waters, bays, lakes, or rivers assigned by the Census boundary file; it is shown separately from land and should not be used to estimate developable land.
