Victor Frederick William Cavendish-Bentinck, 9th Duke of Portland KCMG (18 June 1897 – 30 July 1990), known as Victor Cavendish-Bentinck until 1980, was a British diplomat, businessman, and peer. He served as Chairman of the Joint Intelligence Committee during the Second World War and was British Ambassador to Poland between 1945 and 1947.
Cavendish-Bentinck was born in Marylebone, London on 18 June 1897. He was the second son of Frederick Cavendish-Bentinck, whose father, George Cavendish-Bentinck, was a grandson of William Cavendish-Bentinck, 3rd Duke of Portland. Although formally Victor Cavendish-Bentinck he was known informally as Bill. Like other members of his family he informally dispensed with the name "Cavendish", being known simply as Bill Bentinck. He was educated at Wellington College.
Queen Elizabeth II is also descended from the 3rd Duke of Portland through her maternal grandmother Cecilia Cavendish-Bentinck. The Queen and the 9th Duke of Portland were third cousins, once removed.
Cavendish-Bentinck did not pursue a university education, instead entering the diplomatic service in 1919. In 1922, he took charge of administrative arrangements for the Lausanne Conference. He served in the British Embassy in Paris and also in the League of Nations Department in the Foreign Office. Other postings included Athens in 1932 and Santiago in 1933. The high point of his diplomatic career came in 1939 when he was appointed chairman of the Joint Intelligence Committee. He managed to develop the body as a highly effective instrument of government and, as a result, became counsellor to the Services Liaison Department of the Foreign Office in 1942.
