John George Macleod (8 May 1915 in Kirkhill – 4 April 2006 in Edinburgh) was a Scottish doctor of medicine and a writer of medical textbooks.
On 21 December 1942, John George Macleod married in Edinburgh Nancie Elizabeth Clark.
Macleod was educated at George Watson's College and studied medicine at the University of Edinburgh, where he graduated in 1938.
These two textbooks played a crucial part in keeping Edinburgh on the world map of medicine and were translated into many languages such as Japanese and Russian.
During State visits Macleod sometimes was the duty physician at Holyrood Palace and on one occasion received a gift from the French president Giscard D'Estaing ( a dish with his initials).
