Diyu (Sanskrit: नरक "Naraka") is the realm of the dead or "hell" in Chinese mythology. It is loosely based on a combination of the Buddhist concept of Naraka, traditional Chinese beliefs about the afterlife and a variety of popular expansions and re-interpretations of these two traditions.

Diyu is typically depicted as an underground maze with various levels and chambers, to which souls are taken after death to atone for the sins they committed when they were alive. The exact number of levels in Diyu and their associated deities differ between Buddhist and Taoist interpretations. Some speak of three to four "courts"; others mention "Ten Courts of Hell", each of which is ruled by a judge (collectively known as the Ten Yama Kings); other Chinese legends speak of eighteen levels of Hell. Each court deals with a different aspect of atonement and different punishments; most legends claim that sinners are subjected to gruesome tortures until their "deaths", after which they are restored to their original state and the torture repeated.
