The Wind in the Willows is a classic of children's literature by Kenneth Grahame, first published in 1908. Alternately slow-moving and fast-paced, it focuses on four anthropomorphized animal characters in a pastoral version of England. The novel is notable for its mixture of mysticism, adventure, morality, and camaraderie and is celebrated for its evocation of the nature of the Thames Valley.

In 1908, Grahame retired from his position as secretary of the Bank of England. He moved back to Berkshire, where he had lived as a child, and spent his time by the River Thames doing much as the animal characters in his book do—namely, as one of the phrases from the book says, "simply messing about in boats"— and expanding the bedtime stories he had earlier told his son Alistair into a manuscript for the book.
