Sir Keith Grahame Feiling OBE (7 September 1884 – 16 September 1977) was a British historian, biographer and academic. He was Chichele Professor of Modern History at the University of Oxford, 1946–1950. He was noted for his conservative interpretation of the past, showing an empire-oriented ideology in defence of hierarchical authority, paternalism, deference, the monarchy, Church, family, nation, status, and place.
He was born at Elms House, Leatherhead, the son of stockbroker Ernest Feiling and Joan Barbara (née Hawkins). His mother was the sister of novelist Sir Anthony Hope and a first cousin of Kenneth Grahame, who wrote the classic The Wind in the Willows. Keith was educated at Marlborough College, Marlborough, Wiltshire, and Balliol College, Oxford. He graduated with first-class honours in Modern History in 1906.
In 1907, he was appointed lecturer in history at the University of Toronto under Professor George MacKinnon Wrong. Two years later, he returned to Christ Church, Oxford to lecture and resume his studies toward a doctorate. When the First World War began, he was commissioned into the Royal Highlanders. In 1916, he was posted to India and served in Jhansi and Dalhousie. From 1917 to 1919, he worked as secretary to the Central Recruiting Board of India.
Following the war, Feiling returned to Oxford to teach and research. He was chairman of the Board of Modern History during 1922 to 1924, lecturer in Modern History from 1928 until 1936, and Ford's Lecturer in English History, 1931 to 1932. He also founded the Oxford University Conservative Association in 1924. He was Chichele Professor of Modern History at All Souls College, Oxford between 1946 and 1950, after which he retired and became Professor Emeritus. During this time, he also published a number of works.
