Sir James William Olive KBE (1856 – 14 January 1942) was Assistant Commissioner "A" of the London Metropolitan Police from 1920 to 1925.
He was initially posted to "A" Division in Whitehall, but later transferred to Scotland Yard as an administrative officer.
In 1905, after reorganising the whole way in which the river was policed, he was transferred to the command of "X" Division (Kilburn).
He was appointed Knight Commander of the Order of the British Empire (KBE) in June 1924.
He retired on 31 December 1925 after 53 years' service (which may well make him the longest-serving officer in Metropolitan Police history), and died at his home in Kilburn in 1942.
