Battery White, Civil War fortification in Georgetown County, United States.

Battery White is a Confederate artillery battery built in 1862–63 on Mayrant's Bluff above Winyah Bay in Georgetown County, South Carolina. It has earthen ramparts and gun placements for five or six pieces of artillery, positioned to command the bay entrance.

Confederate engineers built Battery White in 1862–63 at Mayrant's Bluff after Union forces took the islands at the mouth of Winyah Bay. General P. G. T. Beauregard reported it armed and completed by November 10, 1862. It was captured without resistance in the final months of the Civil War.

The fortification demonstrates the military engineering techniques of the 1860s through its strategic placement and construction methods at Mayrant's Bluff.

Battery White sits on private land but is open to the public, so visitors should stay on the grounds and respect posted rules. The earthworks are reached on foot; there are no facilities on site, so bring water and plan for coastal weather. The site lies near Winyah Bay in Georgetown County.

On November 11, 1862, two Union gunboats entered Winyah Bay and opened fire on the Mayrant's Bluff works, the only recorded test of the battery. The site was later listed in the National Register of Historic Places and stands on private land that remains open to the public.
