In various Asian religious traditions, the Nagas are a divine, or semi-divine, race of half-human, half-serpent beings that reside in the netherworld (Patala), and can occasionally take human or part-human form, or are so depicted in art. A female naga is called a Nagi, or a Nagini. Their descendents are known as Nagavanshi. According to legend, they are the children of the sage Kashyapa and Kadru. Rituals devoted to these supernatural beings have been taking place throughout South Asia for at least 2,000 years. They are principally depicted in three forms: as entirely human with snakes on the heads and necks, as common serpents, or as half-human, half-snake beings in Hinduism, Buddhism, and Jainism.

Hindu mythology is the body of myths attributed to, and espoused by, the adherents of the Hindu religion, found in Hindu texts such as the Vedas, the itihasa the Puranas, and mythological stories specific to a particular ethnolinguistic group like the Tamil Periya Puranam and Divya Prabandham, and the Mangal Kavya of Bengal. Hindu myths are also found in widely translated popular texts such as the fables of the Panchatantra and the Hitopadesha, as well as in Southeast Asian texts.
