An urmahlullu (Sumerian language: 𒌨𒈤𒇽𒍇 ur-maḫ lu₂-lu₇[needs IPA]) is a fictitious and mythological lion-centaur hybrid creature.

The urmahlullu ("untamed lion man") is a mythical ancient Mesopotamian beast with a lion-centaur appearance.

Urmahlullu also appear in cylinder and square seals found in excavations of the Indus Valley city-state of Kalibangan.

In one scene, a researcher describes a lion-centaur goddess wearing a head-dress with a long pendant whose body merges with that of the tiger.

[4] At this time known as sagittaries, lion-centaurs appear as grotesques in prayer books, gargoyles in churches, and as aquamanilia.
