National scenic area (NSA) is a conservation designation used in Scotland, and administered by NatureScot on behalf of the Scottish Government. The designation's purpose is to identify areas of exceptional scenery and to protect them from inappropriate development. There are currently 40 national scenic areas (NSAs) in Scotland, covering 13% of the land area of Scotland. The areas protected by the designation are considered to represent the type of scenic beauty "popularly associated with Scotland and for which it is renowned". As such they tend to be mainly found in remote and mountainous areas, with a review in 1997 noting a potential weakness of national scenic areas was that the original selection placed undue emphasis on mountainous parts of the country. National scenic areas do however also cover seascapes, with approximately 26% of the total area protected by the designation being marine. The designation is primarily concerned with scenic qualities, although designated national scenic areas may well have other special qualities, for example related to culture, history, archaeology, geology or wildlife. Areas with such qualities may be protected by other designations that overlap with the NSA designation.

NatureScot is the operating name for the body formally called Scottish Natural Heritage. It is an executive non-departmental public body of the Scottish Government responsible for the country's natural heritage, especially its natural, genetic and scenic diversity. It advises the Scottish Government on nature conservation, and acts as a government agent in the delivery of conservation designations, i.e. national nature reserves, local nature reserves, national parks, Sites of Special Scientific Interest (SSSIs), Special Areas of Conservation, Special Protection Areas and the national scenic areas. It receives annual funding from the Government in the form of Grant in Aid to deliver Government priorities for the natural heritage.
