David Clive Wilson, Baron Wilson of Tillyorn, KT, GCMG, FRSE (born 14 February 1935) is a retired Scottish administrator, diplomat and Sinologist. Lord Wilson of Tillyorn was the penultimate Commander-in-Chief and 27th Governor of Hong Kong (from 1987 to 1992). As governor, Wilson had to deal with the fallout in Hong Kong from the 1989 Tiananmen Square protests in Beijing. He also encountered the Vietnamese refugee problem, which steadily grew worse and led to the 1988 policy of repatriating those found not to qualify for refugee status.The 78-kilometre Wilson Trail, containing ten hiking segments aligned north-south in Hong Kong, is named after him, as is the Lord Wilson Heritage Trust established in December 1992 to preserve and conserve Hong Kong’s heritage. Wilson has been married to Natasha Helen Mary, daughter of Bernard Gustav Alexander, since 1967. They have two sons, Peter and Andrew.
