Tamōhuānchān is a mythical location of origin known to the Mesoamerican cultures of the central Mexican region in the Late Postclassic period. In the mythological traditions and creation accounts of Late Postclassic peoples such as the Aztec, Tamoanchan was conceived as a paradise where the gods created the first of the present human race out of sacrificed blood and ground human bones which had been stolen from the Underworld of Mictlan.

In Aztec religion, Ītzpāpalōtl was a striking skeletal warrior and death goddess and queen of the Tzitzimimeh "star demons", who ruled over the paradise world of Tamōhuānchān, the paradise of victims of infant mortality and the place identified as where humans were created. She is the mother of Mixcoatl and is particularly associated with the moth Rothschildia orizaba from the family Saturniidae. Some of her associations are birds and fire. However, she primarily appears in the form of the Obsidian Butterfly.
