Poinsett County

Poinsett County is an administrative division in northeast Arkansas with rolling terrain shaped by agricultural use and natural features. The landscape is crossed by the L'Anguille River, which flows through farmland and woodland areas.

The county was established in 1838 and named after Joel Roberts Poinsett, a prominent figure in American history. The county seat relocated to Harrisburg in 1859, becoming the center of local government.

The Southern Tenant Farmers Union emerged in Tyronza in 1935 as a grassroots movement of farm workers organizing for better treatment and working conditions. This organization became a notable voice for agricultural laborers across the region.

County offices in Harrisburg operate on standard business days and provide administrative services to the public. Plan your visit during weekday hours to access services and local government resources.

Lake Poinsett State Park sits within the county boundaries and features natural water areas and recreational spaces. The park provides outdoor opportunities that many travelers overlook when exploring the region.
