Iusaaset (also spelled Iusaas, Iusaasit, or Iusaast) is an ancient Egyptian goddess who was one of the earliest deities worshipped in the region. She is often considered a personification of the land of Egypt itself, particularly the fertile silt that was deposited by the annual flooding of the Nile River. Her name translates to "the great one" or "the august one" in Egyptian, reflecting her importance in the early religious landscape. In Hebrew, her name can be transliterated as אוסאס, though there is no direct equivalent or translation. Iusaaset was particularly venerated in the predynastic and early dynastic periods of ancient Egypt, and she was often associated with the creation and sustenance of life. She was sometimes depicted as a cow goddess, emphasizing her role in nurturing and providing for the people. Over time, her attributes and roles were absorbed into those of other deities, such as Hathor and Nut, as the Egyptian pantheon evolved.
