Dally Castle is a ruined 13th-century stone motte-and-bailey fortress in Northumberland, and one of the first hall houses in Northumberland. It lies 5 miles (8.0 km) west of Bellingham Castle, and 4 miles (6.4 km) west of Bellingham on the Chirdon Burn, a tributary of the North Tyne. Dally Castle House was built in the 18th century next to the castle. Across the road lies a small flour mill used to grind wheat during the Napoleonic War.
