Nāga

In various Asian religious traditions, the Nagas (Sanskrit: नाग, romanized: Nāga) 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 and Nair. 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.

Nagaraja is the title given to the king of the nagas. Narratives of these beings hold cultural significance in the mythological traditions of many South Asian and Southeast Asian cultures, and within Hinduism and Buddhism. Communities such as the Nagavanshi, Nair, Khmer and Eelamese claim descent from this race.
