The Story of A Fierce Bad Rabbit is a children’s book written and illustrated by Beatrix Potter, and first published by Frederick Warne & Co. in December 1906.

The book was intended for babies and very young children, and was originally published on a strip of paper that folded into a wallet and was tied with a ribbon.

[1] Potter was experimenting with toy books at the time and A Fierce Bad Rabbit was published for Christmas 1906 in a panorama format of fourteen pictures and text printed from left to right on a long strip of paper that folded accordion-fashion into a wallet tied with a ribbon.

[2][3] The format was popular with readers but unpopular with booksellers who found the item too difficult to keep folded, tied, and in its place once curious customers opened and examined it.

In their simplicity and unusual format, these stories were intended for babies and very young children, but Potter was never at her best when writing for a clearly defined audience.

[6] A Fierce Bad Rabbit focuses on a traditional rather than a creative approach to storytelling and reflects Potter's inexperience with babies and very young children.

The Prime Minister states that Britain is "a nation of fierce, bad rabbits," and that Potter, more than any other writer, influenced his personal prose style.
