Miller County is a county located in the southwestern corner of the U.S. state of Arkansas. As of the 2020 census, the population was 42,600.[3] The county seat is Texarkana.[4]
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,[5] from a portion of neighboring Lafayette County.[6]
