Chinese mythology (traditional Chinese: 中國神話; simplified Chinese: 中国神话; pinyin: Zhōngguó shénhuà) is mythology that has been passed down in oral form or recorded in literature throughout the area now known as Greater China. Chinese mythology encompasses a diverse array of myths derived from regional and cultural traditions. Populated with engaging narratives featuring extraordinary individuals and beings endowed with magical powers, these stories often unfold in fantastical mythological realms or historical epochs. Similar to numerous other mythologies, Chinese mythology has historically been regarded, at least partially, as a factual record of the past.

Along with Chinese folklore, Chinese mythology forms an important part of Chinese folk religion and of religious Taoism. Many narratives recounting characters and events from ancient times exhibit a dual tradition: one that presents a more historicized or euhemerized interpretation, and another that offers a more mythological perspective.

Numerous myths delve into the creation and cosmology of the universe, exploring the origins of deities and heavenly inhabitants. Some narratives specifically address the topic of creation, unraveling the beginnings of things, people, and culture. Additionally, certain myths are dedicated to the genesis of the Chinese state. A subset myths provides a chronology of prehistoric times, often featuring a culture hero who taught people essential skills ranging from building houses and cooking to the basics of writing. In some cases, they were revered as the ancestor of an ethnic group or dynastic families. Chinese mythology is intimately connected to the traditional Chinese concepts of li and qi. These two foundational concepts are deeply entwined with socially oriented ritual acts, including communication, greetings, dances, ceremonies, and sacrifices.

Significant interplay exists between Chinese mythology and the philosophical traditions of Confucianism, Taoism, and Buddhism. Elements of pre-Han dynasty mythology such as those in Classic of Mountains and Seas were adapted into these belief systems as they developed (in the case of Taoism), or were assimilated into Chinese culture (in the case of Buddhism). Conversely, teachings and beliefs from Confucianism, Taoism, and Buddhism have, in turn, become integral components of Chinese mythology. For example, the Taoist belief of a spiritual paradise became incorporated into mythology as the place where immortals and deities dwell. Sometimes mythological and religious ideas have become widespread across China's many regions and diverse ethnic societies. In other cases, beliefs are more limited to certain social groups, for example, the veneration of white stones by the Qiang. One mythological theme that has a long history and many variations involves a shamanic world view, for example in the cases of Mongolian shamanism among the Mongols, Hmong shamanism among the Miao people, and the shamanic beliefs of the Qing dynasty from 1643 to 1912, derived from the Manchus. Politically, mythology was often used to legitimize the dynasties of China, with the founding house of a dynasty claiming a divine descent.

Elaborations on the wuxing are not really part of mythology, although belief in five elements could appear. The Hundred Schools of Thought is a phrase suggesting the diversity of philosophical thought that developed during the Warring States of China. Then, and subsequently, philosophical movements had a complicated relationship with mythology. However, as far as they influence or are influenced by mythology, divides the philosophical camps into two rough halves, a Liberal group and a Conservative group. The liberal group being associated with the idea of individuality and change, for example as seen in the mythology of divination in China, such as the mythology of the dragon horse that delivered the eight bagua diagrams to Fu Xi, and methods of individual empowerment as seen in the Yi Jing (Book of Changes). The Liberal tendency is towards individual freedom, Daoism, and Nature. The relationship of the Conservative philosophies to mythology is seen in the legendary Nine Tripod Cauldrons, mythology about the emperors and central bureaucratic governance, Confucianism, written histories, ceremonial observances, subordination of the individual to the social groups of family and state, and a fixation on stability and enduring institutions. The distinction between the Liberal and Conservative is very general, but important in Chinese thought. Contradictions can be found in the details, however these are often traditional, such as the embrace by Confucius of the philosophical aspects of the Yi Jing, and the back-and-forth about the Mandate of Heaven wherein one dynasty ends and another begins based according to accounts (some of heavily mythological) where the Way of Heaven results in change, but then a new ethical stable dynasty becomes established. Examples of this include the stories of Yi Yin, Tang of Shang and Jie of Xia or the similar fantastic stories around Duke of Zhou and King Zhou of Shang

Mythology exists in relationship with other aspects of society and culture, such as ritual. Various rituals are explained by mythology. For example, the ritual burning of mortuary banknotes (Hell Money), lighting fireworks, and so on.

A good example of the relationship between Chinese mythology and ritual is the Yubu, also known as the Steps or Paces of Yu. During the course of his activities in controlling the Great Flood, Yu was supposed to have so fatigued himself that he lost all the hair from his legs and developed a serious limp. Daoist practitioners sometimes incorporate a curiously choreographed pedal locomotion into various rituals. Mythology and practice, one explains the other: in these rituals, the sacred time of Yu merges with the sacral practice of the present.

Various ideas about the nature of the earth, the universe, and their relationship to each other have historically existed as either a background or a focus of mythologies. One typical view is of a square earth separated from a round sky by sky pillars (mountains, trees, or undefined). Above the sky is the realm of Heaven, often viewed of as a vast area, with many inhabitants. Often the heavenly inhabitants are thought to be of an "as above so below" nature, their lives and social arrangements being parallel to those on earth, with a hierarchical government run by a supreme emperor, many palaces and lesser dwellings, a vast bureaucracy of many functions, clerks, guards, and servants. Below was a vast under ground land, also known as Diyu, Yellow Springs, Hell, and other terms. As time progressed, the idea of an underground land in which the souls of the departed were punished for their misdeeds during life became explicit, related to developments in Daoism and Buddhism. The underground world also came to be conceived of as inhabited by a vast bureaucracy, with kings, judges, torturers, conductors of souls, minor bureaucrats, recording secretaries, similar to the structure of society in the Middle Kingdom (earthly China).
