Captain Frederick Marryat was a Royal Navy officer and a novelist. He is noted today as an early pioneer of nautical fiction, particularly for his semi-autobiographical novel Mr Midshipman Easy (1836). He is remembered also for his children's novel The Children of the New Forest (1847). In addition, he developed a widely used system of maritime flag signalling, known as Marryat's Code.

Nautical fiction, frequently also naval fiction, sea fiction, naval adventure fiction or maritime fiction, is a genre of literature with a setting on or near the sea, that focuses on the human relationship to the sea and sea voyages and highlights nautical culture in these environments. The settings of nautical fiction vary greatly, including merchant ships, liners, naval ships, fishing vessels, life boats, etc., along with sea ports and fishing villages. When describing nautical fiction, scholars most frequently refer to novels, novellas, and short stories, sometimes under the name of sea novels or sea stories. These works are sometimes adapted for the theatre, film and television.
