Blytheville is one of two county seat and the largest city in Mississippi County, Arkansas, United States. It is approximately 60 miles (100 km) north of West Memphis. The population was 13,406 at the 2020 census, down from 15,620 in 2010.

Blytheville was founded by Methodist clergyman Henry T. Blythe in 1879. It received a post office the same year, was incorporated in 1889, and became the county seat for the northern half of Mississippi County (Chickasawba District) in 1901. Blytheville received telephone service and electricity in 1903, and natural gas service in 1950.

Forestry was an early industry, spurred by the massive harvesting of lumber needed to rebuild Chicago following the Great Fire of 1871. The lumber industry brought sawmills and a rowdy crowd, and the area was known for its disreputable saloon culture during the 1880s and 1890s. The Paragould Southeastern Railway, which served the logging industry, arrived in town in 1907.

The cleared forests enabled cotton farming to take hold, encouraged by ongoing levee building and waterway management; the population grew significantly after 1900. On Blytheville's western edge lies one of the largest cotton gins in North America. Soybeans and rice have also become important crops.

The area northwest of the town was developed into a B-25 pilot training school for the Army Air Forces in 1942. The school hosted the BT-13, AT-6, AT-9, and AT-10. The facility closed after the end of WW2 and briefly served as the city's municipal airport.

The area around Blytheville continues to be farmed, though family farms have given way to large factory operations.

In the 1980s, Blytheville began to develop an industrial base, much of which centered on the steel industry. Nucor Steel opened a plant east of Blytheville, on the Mississippi River, in 1987.

The former Blytheville Army Airfield was reopened by the Air Force in 1956 as Blytheville Air Force Base, and from 1959 to 1991 hosted the 97th Wing as part of the Strategic Air Command's Ground Alert Program. The base was closed in December 1992 as part of the 1991 BRAC Commission.

James Sanders was elected as the mayor of Blytheville in 2011. He was the first African-American to serve in that position. After James Sanders’ retirement in 2023, local accountant and veteran Melissa Logan was elected as the city’s first female black mayor.
