Sir Percy Wyn-Harris (24 August 1903 – 25 February 1979) was an English mountaineer, colonial administrator, and yachtsman. He worked in the Colonial Service in Africa and served as Governor of the Gambia from 1949 to 1958. In 1929, he met mountaineer Eric Shipton and together they climbed the twin peaks of Mount Kenya, making the first ascent of Nelion, the secondary summit. A member of Hugh Ruttledge's 1933 Mount Everest expedition, Wyn-Harris reached Edward Norton's record height of 8,573 metres. At around 8,460 metres, he discovered an ice axe, which was almost certainly a remnant of Mallory and Irvine's ill-fated attempt at the first ascent in 1924. Wyn-Harris returned to Everest in 1936, in an expedition again led by Hugh Ruttledge.
