Bhishan Bhairav is a significant deity worshipped in Varanasi (also known as Kashi), which is one of the holiest cities in India. Bhishan Bhairav is considered to be an incarnation of Lord Shiva and is regarded as a fierce form of the deity. The word "Bhishan" means "terrible" or "terrifying," and therefore, Bhishan Bhairav is believed to be a deity who can be both fearsome and benevolent depending on the situation.

This deity is also known as Bhoot Bhairav.
