Arkansas county geography overview
Arkansas has 75 counties, which places it 18th among the 50 state and District of Columbia maps in this atlas when ordered by number of county-level units. Their combined 51,992 square miles of land place the state 27th by mapped land area.
The average county-level area is 693 square miles, while the median is 647.2 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 9% of the state’s mapped land area.

Union County is the largest county-level unit by land area at 1,039.1 square miles. It represents about 2% of all mapped land in Arkansas. At the other end of the range, Lafayette County has 529.5 square miles of land.

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 Arkansas counties
The table is alphabetical, so it works as a name and FIPS-code reference rather than an area ranking. Every identifier begins with the Arkansas state FIPS prefix 05. 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.
