Margaret Gatty (née Scott; 3 June 1809 – 4 October 1873) was an English children's author and writer on marine biology. In some writings she argues against Charles Darwin's Origin of Species. She became a popular writer of tales for young people, which she hoped would influence adult minds as well. Among her other books are Parables from Nature, Worlds not Realized, Proverbs Illustrated, and Aunt Judy's Tales. She edited Aunt Judy's Magazine, a family publication written by various family members.
