Scotney Castle is an English country house with formal gardens south-east of Lamberhurst in the valley of the River Bewl in Kent, England. It belongs to the National Trust.
The gardens, which are a celebrated example of the Picturesque style, are open to the public. The central feature is the ruins of a medieval, moated manor house, Scotney Old Castle, which is on an island on a small lake. The lake is surrounded by sloping, wooded gardens with fine collections of rhododendrons, azaleas and kalmia for spring colour, summer wisteria and roses, and spectacular autumn colour.
