John S Bibby B.S.c. (born 1935) is a British geologist. He was a member of the British Antarctic Survey which undertook four major geological surveys in the James Ross Island Group in 1958 and 1959. The first survey took 69 days in June–August 1958, and served as a reconnaissance of Bald Head, Botany Bay and the west coast of James Ross Island. The party of three hauled their own sledge but were supported and supplied by dog sledge. In September and October 1958 a further 52-day journey was undertaken, this time by dog sledge (which proved considerably more convenient). On this journey a plane table survey on a scale of 1:10,000 was carried out south-west of Brandy Bay, and on 1:20,000 over the Hidden Lake and Tumbledown Cliffs area.
