Augusta Marryat (1834? - 1898?) was a British author. The daughter of author Capt. Frederick Marryat and his wife Catherine, she was a children's author and illustrator perhaps best known fpr the adventure novel Left to Themselves: A Boy's Adventure in Australia (1878), which in later editions had acquired the title The Young Lamberts. The novel is set in Australia, but she is not known to have ever visited the country.
Her sisters Florence and Emilia were also authors: Augusta wrote adventure fiction heavily infused with morality in her father's vein, and Florence was a prolific author of sensationalist novels who also acquired a reputation for hanging out with spiritual mediums.
