Derwent Island House (often called Derwent Isle House) is an 18th-century Italianate house standing on Derwent Island at the centre of Derwentwater in Cumberland. The house on this little wooded isle makes this the only inhabited island in the Lake District. In 1778 Joseph Pocklington bought the island (then known as Vicars Island) for £300 and built a house, boathouse, fort and battery, and Druid circle folly on the land. The house was one of the earliest villas to be built in the Lake District. In 1844 the house was sold to Henry Marshall, a wealthy flax-spinning entrepreneur from Leeds. Marshall called in the popular architect Anthony Salvin to extend the house with a three-storey tower and a large dining room. The house stands within a period garden that has now been restored. The interiors are furnished in neoclassical style. In 1951, Mr Marshalls grandson Denis Marshall gave the property to the National Trust. It is within the council area of Cumberland.
