John Cameron, Lord Cameron, KT, DSC, PRSE, FBA (8 February 1900, London – 30 May 1996, Edinburgh) was a Scottish judge and President of the Royal Society of Edinburgh from 1973 to 1976.
Cameron was born in London, the son of John Cameron, a solicitor from Edinburgh. He attended Edinburgh Academy from 1910–17. He then studied Law at Edinburgh University. This was interrupted by the First World War during which he served as a midshipman in the Royal Naval Volunteer Reserve. He resumed his studies after the war and qualified as an advocate in 1924. In 1936 he rose to be King's Counsel. In the Second World War he returned to the RNVR, this time as a lieutenant-commander, and participated both in the evacuation at Dunkirk and the D-Day landings.
In 1945 he was made Sheriff of Inverness and served in this role until 1948. He returned to Edinburgh in 1948 to serve as Dean of the Faculty of Advocates. He was knighted in 1954 and elected a Senator of the College of Justice on 5 July 1955. All Senators of the College (which includes the Supreme Courts of Scotland) have the honorific, The Honourable, and use the title Lord or Lady along with a surname or a territorial name. Lord Cameron continued as Senator of the College of Justice until 1988. He was elected a Fellow of the Royal Society of Edinburgh in 1949. He became their Vice-President in 1970 and President in 1973. Lord Cameron, who had been awarded the Distinguished Service Cross as a naval officer, was also appointed a Knight of the Order of the Thistle in 1978.
