Nantwich Castle was a Norman castle in Nantwich, Cheshire, England, built before 1180 to guard a ford across the River Weaver. The castle is first documented in 1288. It was last recorded in 1462, and was in ruins by 1485. No trace now remains above ground; excavations in 1978 near the Crown Inn uncovered terracing and two ditches, one or both of which possibly formed the castle's bailey.
