God's Wife of Amun (Egyptian: ḥm.t nṯr n ỉmn) was the highest-ranking priestess of the Amun cult, an important religious institution in ancient Egypt. The cult was centered in Thebes in Upper Egypt during the Twenty-fifth and Twenty-sixth dynasties (circa 740–525 BC). The office had political importance as well as religious, since the two were closely related in ancient Egypt.
Although the title is first attested in the Middle Kingdom, its full political potential was not realized until the advent of the Eighteenth Dynasty.
