Cross County is a rural Northeast Arkansas county in the Arkansas Delta. Created as Arkansas's 53rd county on November 15, 1862, Cross County contains four incorporated municipalities, including Wynne, the county seat and most populous city. It is named for Confederate Colonel David C. Cross, a political leader in the area.

The county is largely flat and fertile, mostly used for row agriculture typical of the rich alluvial soils of the Arkansas Delta. Crowley's Ridge, a forested deposit of loess hills rising from the flat Delta bisects the county from north to south, including part of Wynne and most of Village Creek State Park, the county's primary protected area of ecological value. Historical and cultural features range from Parkin Archeological State Park, which preserves a prehistoric Native American mound building settlement, to the Johnston Cotton Gin marking mechanization of the cotton farm, and the Northern Ohio School, a segregated school built by a lumber company for African-American children of employees.

Cross County occupies 622.33 square miles (1,612 ha) and contained a population of 16,833 as of the 2020 census. The economy is largely based on agriculture. Poverty and unemployment rates are above national averages, household incomes are below state and national averages.

Cross County is mostly served by two school districts: Cross County School District and Wynne Public Schools. Higher education is provided at the Wynne campus of East Arkansas Community College, a public community college. Crossridge Community Hospital in Wynne is a community hospital providing primary care in the county. Although no Interstate highways serve Cross County, the county has access to two United States highways (US Highway 49 [US 49] and US 64) and thirteen Arkansas state highways. Cross County is also served by one public owned/public use general aviation airport, Wynne Municipal Airport, and seven community water systems provide potable water to customers in the county.

Cross County was formed in November 1862 by the Arkansas State Legislature from portions of St. Francis, Crittenden, and Poinsett Counties. The first county seat was Whittsburg, located due east of modern Wynne.

In 1882, the first railroad, the Helena & Iron Mountain Railroad, was constructed in Cross County. The line was later bought out by the St. Louis, Iron Mountain, & Southern Railroad. In 1903, the county seat was moved to Wynne.

Cross County is established on the rich, fertile, alluvial soils of the Mississippi Alluvial Plain. In Arkansas, this region is called the Arkansas Delta (in Arkansas, usually referred to as "the Delta"), having a distinct history and culture from adjacent regions. Bisecting the county from north to south is Crowley's Ridge, a geologic anomaly rising from the Delta composed of loess soil and generally remains covered in oak-hickory forest. Today, the majority (68 percent) of the county is used for row agriculture.

Roughly the western third of the county is within the Western Lowlands Pleistocene Valley Train subregion of the Delta. This region is characterized as flat windblown deposits of silty, sandy soils, and loess with a high groundwater table. Post oak and loblolly pine are native in the higher elevations, with overcup oak, water hickory, willow oak, and pin oak and pondberry native in wetlands. Today, row agriculture is extensive (mostly soybeans and cotton), with commercial aquaculture (crawfish, baitfish, and catfish farms) also common.

Crowley's Ridge is a series of loess hills more closely associated with the Appalachian Mountains of Tennessee and Kentucky than the Delta country surrounding it. Composed of sandy loess stacked on gravel deposits later eroded by streams into ravines, Crowley's Ridge rises from the flat Delta by up to 500 feet (150 m). Crowley's Ridge remains largely wooded with oak-hickory forest or beech–maple forest, with little land in cultivation. Forests are related to the Appalachian cove forests, with post oak, blackjack oak, southern red oak, white oak, beech and sugar maple forest standing in contrast to the southern floodplain forests in the rest of Cross County.

The eastern third of Cross County is split between the Northern Holocene Meander Belts and St. Francis Lowlands, both subregions historically influenced by the Mississippi River. Both regions are flat, poorly drained areas consisting of former river channels, drainageways, and floodplains drained in the late 19th century for settlement and row agriculture. Today consisting of farm fields, channelized drainage ditches, levees, the area is predominantly in soybean and cotton cultivation, with some corn, wheat, rice, and sorghum. Remaining natural areas consist of sugarberry, elm, ash tree, pecan, cottonwood, and sycamores. Sandy "Sunk lands" are attributed to the 1811–12 New Madrid earthquakes.

Given Cross County's position along the Mississippi Flyway, many natural areas and grain fields serve as wintering ground for water fowl. Duck hunting is popular in the Delta, including Cross County.

According to the U.S. Census Bureau, the county has a total area of 622.33 square miles (1,611.8 km), of which 615.85 square miles (1,595.0 km) is land and 6.48 square miles (16.8 km) (1.0%) is water. It ranks 49th of the 75 Arkansas counties in area.

The county is located approximately 46 miles (74 km) south of Jonesboro, 48 miles (77 km) west of Memphis, Tennessee, and 105 miles (169 km) east of Little Rock. Cross County is surrounded by five other Delta counties: Crittenden County to the east, St. Francis County to the south, Woodruff County to the west, Jackson County to the northwest, and Poinsett County to the north.

Water is an important part of Cross County's geography, history, and culture. Hydraulically, the county is split into two watersheds by Crowley's Ridge, with the eastern half draining to the St. Francis River or its tributaries, and the western half draining to the L'Anguille River.

The deep, wide, calm, and navigable St. Francis River has been important for every civilization in Cross County since prehistory. The Casqui tribe settled in the area where the Tyronza River empties into the St. Francis. Today, this settlement is preserved within Parkin Archaeological State Park. Centuries later, European settlers founded Wittsburg as a port city as the northernmost navigable point on the St. Francis a few miles downstream from Parkin, opening the region to regional trade. Within the county, Brushy Creek, Cross County Ditch, Copeland Slough, Prairie Creek, and Village Creek are important watercourses.

The largest protected area in Cross County is Village Creek State Park on Crowley's Ridge near Wynne. The park is known as a large section of preserved forest in its natural state within the Delta, a 27-hole golf course, catfish and bass fishing in the two lakes, horseback riding trails, and a hiking trail along the former Memphis to Little Rock Military Road. The Parkin Archeological State Park in Parkin preserves a prehistoric Native American mound building settlement.

The Brushy Creek Wildlife Management Area is a small property reforested in bottomland hardwood forest by the Arkansas Game and Fish Commission near Hickory Ridge. The Arkansas Natural Heritage Commission maintains the Wittsburg Natural Area as natural Crowley's Ridge habitat, but there is no legal public access to the area.

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 Cross County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.

Cross County is not served by any Interstate highways; the nearest access to the Interstate system is Interstate 40 (I-40) in St. Francis County to the south. Two United States highways serve Cross County: U.S. Highway 49 (US 49) runs north–south in western Cross County; and US 64 runs east–west across the length of Cross County.

Eleven state highways serve the traveling public in the county, varying from short connector routes to long highways traversing the entire county. Highway 1, which runs north–south the length of the Arkansas Delta, essentially bisects the county, serving as a principal arterial through Wynne and connecting Cherry Valley and Vanndale to the state highway system. Highway 42 runs east–west across the northern part of Cross County through Hickory Ridge, Cherry Valley, Birdeye, Coldwater, and Twist. Highway 75 runs north–south through east Cross County, connecting Parkin and Coldwater to I-40 to the south and I-555 to the north.

Highway 163 begins at Wittsburg and runs north along Crowley's Ridge to Birdeye and toward Jonesboro. It is designated as the Crowley's Ridge Parkway, a National Scenic Byway and Arkansas Scenic Byway.

Entergy Arkansas is the sole provider of electricity in most of Cross County, with exception of an area northeast of Wynne roughly between Highway 1 and the St. Francis River, which is served by Woodruff Electric Cooperative. Telephone communication service is provided by AT&T, cable television is provided by East Arkansas Video. Centerpoint Energy is the natural gas utility in Cross County.

The Arkansas Department of Health (ADH) is responsible for the regulation and oversight of public water systems throughout the state. Cross County contains seven community water systems. Cross County Rural Water System is the largest by customer count (9276), though it extends into portions of five other counties. Wynne Water Utilities is largest by customers in Cross County (8837), followed by the Vanndale-Birdeye Water Association (2389). Cherry Valley Waterworks, Hickory Ridge Waterworks, Parkin Rural Water Association, and Parkin Water Company are all smaller water systems with under 1000 customers. All use groundwater from various aquifers as source water.
