The Water-Babies, A Fairy Tale for a Land Baby is a children's novel by Charles Kingsley. Written in 1862–63 as a serial for Macmillan's Magazine, it was first published in its entirety in 1863. It was written as part satire in support of Charles Darwin's The Origin of Species. The book was extremely popular in England, and was a mainstay of British children's literature for many decades, but eventually fell out of favour in part due to its prejudices (common at the time) against Irish, Jews, Catholics and Americans.
