Duplin County, located in the Coastal Plain region of North Carolina, was formed in 1750 from New Hanover County and named for Thomas Hay, Lord Duplin, a member of the English Board of Trade and Plantations. Early inhabitants of the area included the Tuscarora and Siouan Indians, followed by English, Swiss, Scotch-Irish, and German settlers. Kenansville, the county seat, was incorporated in 1852 and named for James Kenan, one of the town's founders. Other communities in the county include Beulaville, Calypso, Magnolia, Rose Hill, Wallace, and Warsaw. Notable physical features of the county include the Northeast Cape Fear River, Muddy Creek, Bear Swamp, Maxwell Mill Pond, and Picadilly Bay.

Duplin County boasts several historic attractions, among them the Kenansville Historic District, with notable examples of Greek Revival architecture, and the Dickson Farm, dating from the early nineteenth century. Kenansville is the site of Liberty Hall Plantation, ancestral home of the Kenan family. County cultural institutions include the Cowan Museum (a collection of unusual American artifacts), the William Rand Kenan Memorial Amphitheatre, and the Tar Heel Fine Arts Society. The Duplin Winery is the oldest winery in North Carolina, established in the 1960s. The county also hosts many annual festivals and events, such as the Warsaw Veterans Day Celebration (the nation's oldest continuously celebrated Veterans Day event), the North Carolina Pickle Festival, the North Carolina Poultry Jubilee, and Beach Music at the Winery.

Agriculture is a key part of the Duplin County economy, and goods produced include tobacco, cotton, cucumbers, strawberries, corn, soybeans, wheat, barley, sweet potatoes, Christmas trees, turkeys and other poultry, hogs, and beef and dairy cattle. Manufactured products include textiles, pickles, apparel, and frozen foods. Duplin County's population was estimated to be 51,500 in 2004.
