Its name honours Henry Cecil Gunning (1901–1991) of the Geological Survey of Canada and a professor at the University of British Columbia.<ref name=Mindat/>
==Occurrence== Gunningite is rare. It is found in dry areas of the oxidized portions of sphalerite-bearing deposits. It has been noted in mines in Canada (Yukon Territory, British Columbia and New Brunswick), the United States (Nevada and Arizona), Switzerland (Valais), Greece (Attica) and Germany (Baden-Württemberg).
