Catherine Cranston (27 May 1849 – 18 April 1934), widely known as Kate Cranston or Miss Cranston, was a leading figure in the development of the social phenomenon of tea rooms. She is nowadays chiefly remembered as a major patron of Charles Rennie Mackintosh and Margaret MacDonald in Glasgow, Scotland, but the name of Miss Cranston's Tea Rooms lives on in reminiscences of Glasgow in its heyday.
