Miller County is a county located in the southwestern corner of the U.S. state of Arkansas. As of the 2010 census, the population was 43,462. The county seat is Texarkana.

Miller County is part of the Texarkana, TX-AR, Metropolitan Statistical Area.

When first formed, Miller County was Arkansas's sixth county, established on April 1, 1820, and named for James Miller, the first governor of the Arkansas Territory. Additionally, Miller County was the first of the state's counties to be formed upon the creation of the Arkansas Territory. The first five — Arkansas, Lawrence, Clark, Hempstead and Pulaski — were formed during Arkansas's days as part of the Missouri Territory. This county was abolished in 1838.

During the Reconstruction era, it was organized again on December 22, 1874 from a portion of neighboring Lafayette County.


Miller County was originally created in 1820 and included most of the current Miller County as well as most of what are now counties in Texas: Bowie, Red River, Lamar, Fannin, Cass, Morris, Titus, Franklin, Hopkins, Delta, and Hunt. In 1831 the county seat was located what is the current day Clarksville, Texas. When Arkansas achieved statehood the same year Texas declared itself an independent republic in 1836 a dispute over the common border arose, with the area in Miller County having representation in both the Arkansas legislature and the Texas congress. In 1837 and 1838, Texas organized Red River and Fannin counties, respectively, in the area. Arkansas attempted to counter by making it a misdemeanor for Miller County residents to hold office in Texas, and then by establishing a county court in Fannin. The attempts were ultimately unsuccessful, and in 1845 Texas was annexed by the United States, settling the boundary between Texas and Arkansas. As much of Miller County was lost to Texas, the county was dissolved with the remaining territory returning to Lafayette County.

The modern Miller County was re-created in 1874 from the parts of Lafayette County lying west and south of the Red River.


According to the U.S. Census Bureau, the county has a total area of 638 square miles (1,650 km2), of which 626 square miles (1,620 km2) is land and 12 square miles (31 km2) (1.9%) is water.

Unincorporated communities


Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries. Arkansas townships have limited purposes in modern times. However, the United States Census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Miller County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.


Major highways


The Arkansas Department of Health (ADH) is responsible for the regulation and oversight of public water systems throughout the state. Miller County contains six community water systems: Texarkana Water Utilities (TWU), Fouke Waterworks, Miller County Public Water Authority (PWA), Garland Waterworks, Eastern Cass Water Supply Corporation, and Shady Acres Mobile Home Park. TWU, a joint department between the two Texarkana municipalities, provides drinking water and fire flows on both sides of the state line, including several partner cities in Texas. Its source waters are Lake Millwood in Arkansas and Lake Wright Patman in Texas. Miller County PWA purchases water from TWU, and has the same executive director as of February 2018. The remaining systems have retail populations served under 1,000, and are groundwater systems.
