Naomi Mary Margaret Mitchison, Lady Mitchison, CBE (née Haldane; 1 November 1897 – 11 January 1999) was a Scottish novelist and poet. Often referred to as the doyenne of Scottish literature, she wrote over 90 books covering a wide range of genre including historical, science fiction, travelogue and autobiography. With her husband Gilbert Richard Mitchison becoming a life peer in 1964, she was also entitled to call herself Lady Mitchison, but never used the title herself.
