Hungry ghost is a concept in Chinese Buddhism, Chinese traditional religion, Vietnamese Buddhism and Vietnamese traditional religion representing beings who are driven by intense emotional needs in an animalistic way.

"Hungry ghosts" play a role in Chinese Buddhism, Vietnamese Buddhism and Taoism as well as in Chinese folk religion and Vietnamese folk religion.
