Sir Percy Wyn-Harris KCMG MBE KStJ (24 August 1903 – 25 February 1979) was an English mountaineer, colonial administrator, and yachtsman.
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.
Lewis (2000) claims that in his time in Kenya Wyn-Harris viewed it as "overpopulated and desperately needing urbanization, birth control, and secondary industries.
It was his belief that the Gambia should not progress towards self-government; rather, it should maintain a permanent link with the United Kingdom and be administered locally: what he termed the 'Channel Islands option'.
Wyn-Harris left the Gambia in April 1958, having so upset the Bathurst population that he departed by slipping across the border into Senegal, rather than bowing out in a public ceremony.
After his time in the Gambia, he was a member of the Devlin Commission of Enquiry into the Nyasaland disturbances of 1959 and served as the Administrator of the North Cameroons from October 1960 to June 1961.
