Sir George William Rendel KCMG (23 February 1889 – 6 May 1979) was a British diplomat.
Rendel entered the Diplomatic Service and was the head of the Eastern Department of the Foreign Office from 1930 to 1938.
In 1922 he produced a seven-page British Foreign Office document which detailed the persecution of Greeks and other minorities in the Ottoman Empire.
Rendel stated that throughout the First World War, "it is generally agreed that about 1,500,000 Armenians perished in circumstances of extreme barbarity, and that over 500,000 Greeks were deported, of whom comparatively few survived".
[3] In 1941, he was appointed Envoy Extraordinary and Minister Plenipotentiary to the Kingdom of Yugoslavia, a post held until 1943.
