Highgrove House is the family residence of Charles, Prince of Wales, and Camilla, Duchess of Cornwall, situated south west of Tetbury in Gloucestershire, England. Built in the late 18th century, Highgrove and its estate was owned by various families until it was purchased in 1980 by the Duchy of Cornwall from Maurice Macmillan. Charles remodelled the Georgian house with neo-classical additions in 1987. The duchy manages the estate and the nearby Duchy Home Farm. The house is noted for its extensive gardens which receive more than 30,000 visitors a year.

As the country residence of the heir to the throne, Highgrove House is well protected by security. The house is one of several designated sites proscribed under the Serious Organised Crime and Police Act 2005 that are protected by law from criminal trespass, a high stone wall surrounds the estate, and the duchy and the chief constable of Gloucestershire supported the moving of two public footpaths that ran close to the house for security reasons in 1983. Several people have been arrested in the vicinity of Highgrove since Charles's occupation, including two French journalists and a photographer from The Sun. A 1.5 nautical mile aerial exclusion zone for civilian aircraft and microlights was imposed over Highgrove in 1991.
