Anne Mary Perceval (14 January 1790 – 23 November 1876) was an English-born botanist and author in Lower Canada. The daughter of Sir Charles Flower, Lord Mayor of London, she was born Anne Mary Flower. She married Michael Henry Perceval and came to Quebec City in 1810 when her husband was named customs collector. In 1815, with her husband, she acquired Spencer Wood, where she established an important garden of native plants. She identified about 150 species of plants from her collection to William Jackson Hooker, who included them in his Flora boreali-americana, or, the botany of the northern parts of British America. She also corresponded with botanist John Torrey.
