Enmesharra (Sumerian: 𒀭𒂗𒈨𒊹𒊏 Enmešarra, "Lord of all mes") was a Mesopotamian god associated with the underworld. He was regarded as a member of an inactive old generation of deities, and as such was commonly described as a ghost or resident of the underworld. He is best known from various lists of primordial deities, such as the so-called "theogony of Enlil," which lists many generations of ancestral deities.
