Tatenen (also Ta-tenen, Tatjenen, Tathenen, Tanen, Tenen, Tanenu, and Tanuu) was the deity of the primordial mound in ancient Egyptian religion.

Both feminine and masculine, he was an androgynous protector of nature from the Memphis area (then known as Men-nefer), the ancient capital of the Inebu-hedj nome in Lower Egypt.

Tatenen represented the Earth and was born in the moment it rose from the watery chaos,[1] analogous to the primeval mound of the benben and mastaba and the later pyramids.

He was seen as the source of "food and viands, divine offers, all good things",[4] as his realms were the deep regions beneath the earth "from which everything emerges", specifically including plants, vegetables, and minerals.

[1][6] He also personified Egypt (due to his associations with rebirth and the Nile) and was an aspect of the earth-god Geb, as a source of artistic inspiration,[7] as well as assisting the dead in their journey to the afterlife.
