Xiwangmu, also known by many other local names and titles, is a major goddess in Chinese folk religion and mythology. Associated with eternal bliss, longevity and prosperity, worship of Xiwangmu may date back all the way to the 15th century BCE, though she is mainly associated with Taoism.

Xiwangmu is often portrayed holding court within her palace on the mythical Mount Kunlun, ruling over a paradise of immortals and deities, serving the 'Peaches of Immortality' to her guests. She plays only a minor role in 'Fengshen Yanyi', though her daughter Princess Longji plays a much more significant role.
