Harold Greville Hanbury (19 June 1898 at Compton Verney House, Warwickshire – 12 March 1993 at Pinetown, Natal, South Africa) was Vinerian Professor of English Law at the University of Oxford from 1949 to 1964.
He was the only child of Basil Hanbury and his wife, Patience, née Verney, a daughter of Henry Verney, eighteenth Baron Willoughby de Broke.
He was educated at Charterhouse and took up a Classical Scholarship at Brasenose College, Oxford, in 1915, but interrupted his studies for military service in the British Army in 1916, returning to complete his degree after the end of World War I. In 1921 he was elected a Fellow of Lincoln College, and an Honorary Fellow in 1949.
In that year he was appointed Vinerian Professor of English Law, which carried with it a Fellowship at All Souls College. He remained there until his retirement in 1964, after which he was Dean of the Law Faculty of the University of Nigeria until 1966. He was afterwards a champion of the Biafran cause, and published in 1968 "Biafra: A Challenge to the Conscience of Britain".
In 1980 Margaret, Hanbury's wife, whom he had married in 1927 (a niece of the Danish pathologist Georges Dreyer), died, and he left England to live with a god-daughter in Natal, South Africa, where he died in 1993.
