Harold Leslie Keer Whitehouse (13 April 1917 – 18 January 2000) was a British botanist and bryologist.
He is credited with a discovery of a number of species, as well as with being a president of the British Bryological Society.
Harold Whitehouse entered Queen’s College, University of Cambridge in 1936, and eventually started a PhD in biology under supervision of David Catcheside.
His graduate studies were interrupted by World War II, during which he was detached to the Royal Air Force photographic unit in Medmenham, Buckinghamshire.
After the war, Whitehouse returned to Cambridge and was awarded a PhD on the genetics of ascomycetes.
