Christopher Robin, fictional character, an English boy whose adventures with Winnie-the-Pooh, Piglet, and other animals are the basis of the stories in the classic children’s books Winnie-the-Pooh (1926) and The House at Pooh Corner (1928) by A.A. Milne. The character was based on the author’s young son. In the stories, Christopher Robin is usually the voice of reason and the character who can be relied on to get the animals out of the predicaments they get themselves into. He is also a character in the verse collections When We Were Very Young (1924) and Now We Are Six (1927).
