Buckler's Hard is a hamlet in the civil parish of Beaulieu, in the New Forest district, in the county of Hampshire, England, on the banks of the Beaulieu River.

With its two rows of Georgian cottages running down to the river, Buckler's Hard is part of the 9,000-acre (3,600-hectare) Beaulieu Estate. The hamlet is some 2.5 miles (4.0 km) south of the village of Beaulieu.

Buckler's Hard, originally called Montagu Town, was built by the second Duke of Montagu, and was intended to be a free port for trade with the West Indies. Its geography also favoured the development of shipbuilding, as the hamlet possessed access to a sheltered but navigable waterway with gravel banks capable of supporting slipways for vessel construction and launch. Timber for hulls was also readily available from the surrounding New Forest.

Shipbuilding at Buckler's Hard commenced in the early eighteenth century. A private shipyard adjoining the hamlet was established by James Wyatt, a local entrepreneur and timber merchant from Hythe on Southampton Water. Wyatt & Co. won a contract to build the Navy ship HMS Surprise in 1744, and subsequently another, HMS Scorpion, at Buckler's Hard. Henry Adams, a master shipwright, was sent from Deptford Dockyard to Buckler's Hard in 1744 by the Admiralty to oversee the building of these ships by Wyatt & Co. After the completion of the initial ships by Wyatt, Buckler's Hard grew to national prominence under Henry Adams and won subsequent Royal Navy contracts.

Over the following sixty years, Adams would supervise the building of 43 Royal Navy ships at Buckler's Hard, including three that fought at the Battle of Trafalgar in 1805: HMS Euryalus, HMS Swiftsure, and HMS Agamemnon. The two main shipbuilders associated with the shipyard are Henry Adams and from 1783 his son Balthazar Adams.

Shipbuilding at Buckler's Hard declined in the nineteenth century. During World War II, the village was used to build motor torpedo boats, and the river was a base for hundreds of landing craft for the Normandy invasion, Operation Overlord. Today the hamlet is given over to tourism, with a small maritime museum and a modern yachting marina. Buckler's Hard was where Sir Francis Chichester began and finished his solo voyage around the world in the Gipsy Moth IV.
