King's Daughter (ancient Egyptian: zꜣt nsw) or the extended version King's Daughter of His Body (i.e. Princess) was an ancient Egyptian honorific title held by the daughters of the Pharaoh. The title is the female equivalent of King's Son (i.e. Prince) and was also occasionally given to foreign princesses who were sent into diplomatic marriage with the Egyptian pharaoh.
In rare cases the title was given to granddaughters of the pharaoh, as is the case with princess Nebetia, who was the granddaughter of pharaoh Thutmose IV.
