A toilet god is a deity associated with latrines and toilets. Belief in toilet gods – a type of household deity – has been known from both modern and ancient cultures, ranging from Japan to ancient Rome. Such deities have been associated with health, well-being and fertility and have been propitiated in a wide variety of ways, including making offerings, invoking and appeasing them through prayers, meditating and carrying out ritual actions such as clearing one's throat before entering or even biting the latrine to transfer spiritual forces back to the god.

Ucchuṣma is a Vidyārāja in Mahayana and Vajrayana Buddhism.
