Supply is a small unincorporated community in Brunswick County, North Carolina, United States, located around the intersection of US 17 and NC 211. Its name is derived from the use of the Lockwoods Folly River as a trade route in the 18th and 19th centuries. Residents of the nearby beach communities of Holden Beach, Oak Island, Ocean Isle, Caswell Beach, and Sunset Beach often formerly commuted to Supply for goods and other materials.
