The Black River is a tributary of the Cape Fear River, approximately 50 mi (80 km) long, in southeastern North Carolina in the United States.
It is formed in southern Sampson County, approximately 15 mi. (24 km) south of Clinton, by confluence of two creeks: Great Coharie and Six Runs. It flows SSE, receiving the South River approximately 30 mi (48 km) south of Clinton. It flows southeast through Pender County, past the Moores Creek National Battlefield, and joins the Cape Fear approximately 10 mi (16 km) northwest of Wilmington, near the broadening of the Cape Fear into a tidal estuary.
