Sir Charles Kingsley Webster (25 July 1886 – August 1961) was a Cambridge-trained historian and British diplomat. He was educated at King's College, Cambridge as well as the Merchant Taylors' School, Crosby. After leaving Cambridge University, he went on to become a professor at Harvard, Oxford, and the London School of Economics. He also served as President of the British Academy from 1950-1954.
In addition to his career in academia, Webster worked extensively in the Foreign Office, especially in the United States, and was a leading supporter of the new United Nations, as he had been of the League of Nations.
After studying at Cambridge University, Webster became Professor of International Relations at the University of Wales, Aberystwyth where he wrote his two major books on the foreign policy of Lord Castlereagh, the first (published in 1925) covering the period 1815–1822, the second (published in 1931) that from 1812–1815. In 1932 Webster moved to the newly established Stevenson chair of international relations at the London School of Economics (LSE).
During World War II, he worked extensively in the Foreign Office, especially in the United States, and was a leading supporter of the new United Nations, as he had been of the League of Nations. He attended the first meetings of both the General Assembly and the Security Council in January 1946 and the final meeting of the League of Nations in April. He was made a Knight Commander of the Order of St Michael and St George in the new year's honours list of 1946.
In 1948, Webster gave the Ford Lectures in the University of Oxford. In 1951, his biography of Henry John Temple, 3rd Viscount Palmerston was finally published. He was President of the British Academy in 1950. He was awarded honorary degrees from Oxford, Cambridge Wales, Rome, and Williams College, Massachusetts, and was made an honorary fellow at King's College, Cambridge. He retired from his chair at the LSE in 1953.
