John Ramsay (13 March 1877 – 19 January 1962) was a Scottish magician. He has been described, by Alex Proctor, former President of the Scottish Conjurers' Association, as a "magician's magician, who loved to trick fellow conjurers".
John Ramsay performed at the International Brotherhood of Magicians (IBM) convention in Batavia, New York and Chicago, in 1950. In 1955, he won the micromagic category at the Fédération Internationale des Sociétés Magiques (FISM), held in Amsterdam. He also served as president of the British Ring of the IBM. John Ramsay is the only magician in the world with a garden named after him; Ramsay Gardens, in his native town of Ayr, Scotland.
