Keith Edward Kissack MBE (18 November 1913 – 31 March 2010) was a British schoolteacher and historian. He is notable for his many publications on the history of Monmouth and Monmouthshire.
Kissack was born in Clun, Shropshire, to Rev. Bernard Kebble Kissack and Caroline Keith-Murray. His mother was a descendant of the Murray of Blackbarony family of Scotland, Edmund Murray Dodd, a leading figure in Nova Scotia in the mid 19th Century, and David Mathews, the Mayor of New York City under the British during the American Revolution.
Kissack attended Durham School where he was a member of the school cricket team in 1931 and 1932. He later attended St Mark and St John's College, Chelsea, where he trained as a teacher.
