Princess Nebetah was apparently the fourth daughter of Pharaoh Amenhotep III and Queen Tiye. She is not as well known as her sisters. Her name, which means 'Lady of the Palace' or 'Great Lady', was also a title given to queens. Both her elder sister Henut-Taneb and Nebetah were given names that were traditionally titles of Egyptian queens. Perhaps, during the period in which these two princesses were born, Amenhotep III was trying to keep from honoring any gods in his daughters' names? She is never called a 'King's Wife' and it doesn't seem that she was married to Amenhotep III. Due to her lack of presence on many monmuments that the elder daughters of Tiye appear on, it has been suggested that she was significantly younger than Sitamen, Isis, and Sitamen. Nebetah's ultimate fate, like those of her sisters, is not known.
Nebetah's only known title was 'King's Daughter Whom He Loves.'
