Mary Ann Burnett (died 18 December 1856) was a British botanist, author and editor.
Burnett was the illustrator and editor of Illustrations of Useful Plants employed in the Arts and Medicine (1839âÂÂ40). Some of the text was written by her brother Gilbert Thomas Burnett. Subsequent editions from 1840 onwards name Mary Ann as the author. Burnett dedicated the 1842 edition of the book to her patron, Miss Minshull.
Burnett died at Fitzroy Square, London, in December 1856 "after a long and painful illness".
