The Deer and the Cauldron, also known as The Duke of Mount Deer, is a novel by Jin Yong (Louis Cha) and the last of his works. The novel was initially published in Hong Kong as a serial, and ran from 24 October 1969 to 23 September 1972 in the newspaper Ming Pao. Although the book is often referred to as a wuxia novel, it is not archetypal of the genre, since the protagonist, Wei Xiaobao, is not an adept martial artist, but rather, an antihero who relies on wit and cunning to get out of trouble. Another alternative title of the novel is On Ruding Mountains.
