Tatenen (also Ta-tenen, Tatjenen, Tathenen, Tanen, Tenen, Tanenu, and Tanuu) was the god of the primordial mound in Egyptian Mythology. His name means risen land or exalted earth, as well as referring to the silt of the Nile. As a primeval chthonic deity, Tatenen was identified with creation. He was an androgynous protector of nature from the Memphis area, then known as "Men-nefer".

Tatenen represented the Earth and was born in the moment it rose from the watery chaos, 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", as his realms were the deep regions beneath the earth "from which everything emerges", specifically including plants, vegetables, and minerals. His father was the creator god Khnum, who made him on his potter's wheel of Nile mud at the moment of creation of Earth. This fortuity granted him the titles of both "creator and mother who gave birth to all gods" and "father of all the gods". 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, as well as assisting the dead in their journey to the afterlife.
