Sunflower County is a county located in the U.S. state of Mississippi. As of the 2020 census, the population was 25,971.  Its largest city and county seat is Indianola. 
Sunflower County comprises the Indianola, MS Micropolitan Statistical Area, which is included in the Cleveland-Indianola, MS Combined Statistical Area. It is located in the Mississippi Delta region.

Sunflower County was created in 1844. The land mass encompassed most of Sunflower and Leflore Counties as we know them today. The first seat of government was Clayton, located near Fort Pemberton. Later the county seat was moved to McNutt, also in the Leflore County of today. When Sunflower and Leflore Counties were separated in 1871, the new county seat for Sunflower County was moved to Johnsonville. This village was located where the north end of Mound Bayou empties into the Sunflower River. In 1882 the county seat was moved to Eureka, which was later renamed Indianola.

The county reached its peak population in 1930. After that, population declined from 1940 to 1990. There was considerable migration out of the rural county, especially as mechanization reduced the need for farm labor. Both whites and blacks left the county. Many African Americans migrated north or west to industrial cities to escape the social oppression and violence of Jim Crow, especially moving in the Great Migration during and after World War II, when the defense industry on the West Coast attracted many.

The Mississippi Department of Corrections (MDOC) is responsible for the state's correctional services, probation services, and parole services. MDOC operates the Mississippi State Penitentiary (MSP; colloquially known as 'Parchman Farm') in the unincorporated community of Parchman in Sunflower County and a probation and parole office in the Courthouse Annex in Indianola. 
MSP, a prison for men,   is the location of the State of Mississippi male death row and the State of Mississippi execution chamber.   Around the time of MSP's opening in 1901, Sunflower County residents objected to having executions performed at MSP because they feared that Sunflower County would be stigmatized as a "death county." Therefore, the State of Mississippi originally performed executions of condemned criminals in their counties of conviction. By the 1950s residents of Sunflower County were still opposed to the concept of housing the execution chamber at MSP. In September 1954, Governor Hugh White called for a special session of the Mississippi Legislature to discuss the application of the death penalty.  During that year, an execution chamber was installed at MSP. 
In December 2011, Sunflower County's unemployment rate was 16.2%. The Mississippi statewide rate was 9.9%, and the U.S. overall unemployment rate was 8.3%.

Between 2010 and 2012, the State of Mississippi had taken over all three Sunflower County school districts and put them under the conservatorship of the Mississippi Department of Education,  due to academic and financial reasons. 
In February 2012 the Mississippi Senate voted 43–4 to pass Senate Bill 2330, to consolidate the three school districts into one school district. The bill went to the Mississippi House of Representatives. 
The Greenwood Commonwealth said that the county was an "easy target" for school merging due to the difficulties in all three school districts, and that the scenario "doesn’t leave them with much leverage to argue in favor of the status quo. And because none of them does well, none of them can object to assuming someone else's headaches. All three are beset with them."  Later that month, the State Board of Education approved the consolidation of the Drew School District and the Sunflower County School District, and if Senate Bill 2330 is approved, Indianola School District will be added. 
In May 2012 Governor of Mississippi Phil Bryant signed the bill into law, requiring all three districts to consolidate.  SB2330 stipulates that if a county has three school districts all under conservatorship by the Mississippi Department of Education will have them consolidated into one school district serving the entire county.  As of July 1, 2012, the Drew School District was consolidated with the Sunflower County School District.
