Princess Beketaten (aka Baketaten, Beketaton...), although her parentage is still debated, was in all probability the youngest daughter of Pharaoh Amenhotep III and Queen Tiye.
Her name, which means, "Haidmaiden of Aten," suggests that when she was born, steps towards her elder brother's future reforms were already being taken.
At Amarna, images of Princess Beketaten are closely associated with Queen Tiye, which is the reason why many feel that she was a daughter of the senior royal couple rather than Nefertiti and Akhenaten. She is called a 'King's Daughter', but never, like all of Nefertiti's girls, called 'Kings's Daughter born of the King's Great Wife, Nefernefruaten-Nefertiti,' so the assumption that she may have been the last child of Tiye and Amenhotep III seems to be a likely conclusion.
Her time and manner of death are not known, as around the time of Tiye's death, she ceases to be mentioned.
Princess Beketaten's only known title was 'King's Daughter of His Body'
