The Discworld is the fictional setting for all of Terry Pratchett's Discworld fantasy novels. It consists of a large disc resting on the backs of four huge elephants which are standing on the back of an enormous turtle, named Great A'Tuin as it slowly swims through space. Magic is an everyday feature of life on Discworld, whilst even science has unearthly qualities. The similarities to Planet Earth only exacerbate the strangeness of Discworld itself.

Discworld is a comic fantasy book series written by the English author Terry Pratchett, set on the Discworld, a flat planet balanced on the backs of four elephants which in turn stand on the back of a giant turtle. The series began in 1983 with The Colour of Magic and continued until the final novel The Shepherd's Crown, which was published in 2015, following Pratchett's death. The books frequently parody or take inspiration from classic works, usually fantasy or science fiction, as well as mythology, folklore and fairy tales, and often use them for satirical parallels with cultural, political and scientific issues.
