Gordon Bryant Ogilvie ONZM (8 May 1934 – 23 October 2017) was a New Zealand historian and biographer who wrote over 20 books, mainly about the people, places and institutions of the Canterbury region. He played a considerable role in uncovering the exploits of pioneer aviator Richard Pearse and popularising these for the first time through his 1973 work The Riddle of Richard Pearse. His other major biography, Denis Glover : His Life (1999), was the first full account of this significant figure in New Zealand literature.
