Hugh Buchanan (born 29 May 1958) is a Scottish watercolour painter,[1][2][3] renowned for his detailed draughtsmanship and treatment of light and shadows in interiors, and for a sense of depth and space that is reminiscent of the work of Cotman and Piranesi.

The son of Ian Buchanan, manager of Scottish and Newcastle Breweries, and Fiona Ross, a graduate of the Central School of Art and Design, London, he was born in Edinburgh in 1958.

Over several years he worked on commissions for the National Trust and in 1987 was invited by the Prince of Wales to paint a series of interiors of Balmoral, later completing a further sequence at Highgrove in 1994.

In 2013, The Esterhazy Archive, paintings of documents at Forchtenstein south of Vienna, one of the properties of the Hungarian princely family Esterházy, was shown at Summerhall[7] in Edinburgh.
