Clark County is a county located in the south-central part of the U. S. state of Arkansas. As of the 2010 census, the population was 22,995; the county seat is Arkadelphia. The Arkadelphia, AR Micropolitan Statistical Area includes all of Clark County. Ancient Indigenous peoples occupied areas along the waterways for thousands of years prior to European exploration. Among the various cultures was the Caddoan Mississippian culture, which developed by 1000CE and occupied certain sites in Arkansas at different times; this was the westernmost expression of the Mississippian culture, which developed a vast network and numerous centers of development throughout the Mississippi Valley and its tributaries. The Caddoans constructed substantial earthwork mounds in the areas of Texas. Archeological evidence has established there was unbroken continuity from the Caddoan Mississippian people to the historic Caddo people and related Caddo-language speakers who encountered the first Europeans, their descendants formed the modern Caddo Nation of Oklahoma.

Settlers in the 19th century found earthwork mounds, ten to 15 feet in height, in areas around what developed as Arkadelphia, Arkansas. Some were excavated for pottery and other grave goods. At the time of European-American settlement after the United States acquired this territory in the Louisiana Purchase of 1803, the pioneers encountered three major Native American tribes: the Caddo, who lived along the banks of the Caddo River. Clark County was the third county formed by Americans in Arkansas, on December 15, 1818, together with Hempstead and Pulaski counties; the county is named after William Clark Governor of the Missouri Territory, which included present-day Arkansas. On November 1, 1833, the Arkansas territorial legislature created Pike County from western Clark County and part of northern Hempstead County, it was named after US explorer Zebulon Pike. Arkadelphia was designated as the county seat in 1842, it became important as a hub after railroads were constructed to here that connected with numerous markets.

Timber harvesting became important by the end of the century. By 1890, forest products were ranked next to agriculture in economic importance. In the 20th century, continued modern technological developments established the industry's continued importance in the county's economy. Three of the six lynchings recorded in Clark County from 1877 to 1950 took place in a mass event in late January 1879. An African-American man, Ben Daniels, three of his four sons were arrested as suspects in an alleged robbery and assault of a white man and held in the county jail. Daniels and two of his sons were forcibly taken out of the jail by a white mob and lynched by hanging from trees in the courthouse square, without trial. One son, believed to be Charles Daniels, survived for trial, he was convicted and served in prison until about 1886 or 1887. From 1920 to 1960, the county population declined; the cotton culture had been affected by the invasion of the boll weevil. In this period, many African-American families, who still constituted most of the farm workers left Arkansas and other parts of the rural South to escape Jim Crow oppression and seek better employment in Northern and Midwestern cities in the Great Migration.

In the latter part of this period, some migrated to the West Coast, where the defense industry developed during and after World War II offered higher paying jobs. At the same time, the lumber industry declined causing a loss of jobs. Several companies had operated sawmills and related businesses in Clark County in the early part of the century; the founders of the lumber town Graysonia, Arkansas moved to Springfield, renaming their company as Roseboro Lumber. While manufacturing industries had entered the county, several had a downturn in the 1980s. In the 1970s, the DeGray Dam and Lake were completed along the Caddo River, providing new areas in the county for tourism and recreation, which have become major components of the economy. According to the U. S. Census Bureau, the county has a total area of 883 square miles, of which 866 square miles is land and 17 square miles is water. Interstate 30 U. S.
