Sir Graeme Thomson GCMG KCB (9 August 1875 – 28 September 1933) was a British civil servant in the Admiralty, who served as a colonial civil servant and then governor in several British colonies.

Graeme Thomson was educated at Winchester and New College, Oxford and joined the civil service in 1900, being assigned to the Admiralty.

[1] Shortly after the outbreak of war, he received extremely rapid promotion, from a superintending clerk to Civil Assistant Director of Transport in September 1914 and to Director of Transports at the Admiralty in December,[2][3] succeeding Admiral Savory.

Winston Churchill praised him after stating over a million troops had been moved: The credit for these arrangements lies very largely with the head of the Admiralty Transport Department, Mr. Graeme Thomson—one of the discoveries of the War, a man who has stepped into the place when the emergency came, who has formed, organised, and presided over performances and transactions the like of which were never contemplated by any State in history.

[4]The Adelaide Advertiser described him in 1915 as: A tall, soldierly-looking man with the face of a diplomat, the forehead of a thinker, a square chin, and a bushy moustache, Mr. Thomson's appearance conveys the impression of a rare combination of organising ability, accuracy, judgment, resource, and rapid assimilation of ideas.
