Beketaten (14th century BCE) was an Ancient Egyptian princess of the 18th dynasty. She was the youngest daughter of Pharaoh Amenhotep III and his Great Royal Wife Tiye, thus the sister of Pharaoh Akhenaten[1].
Her name means "Handmaid of Aten", which indicates she was born during the Amarna period, and since on pictures she seems to be the same age as Akhenaten's daughters, some see this as an evidence of a long co-regency between Amenhotep III and Akhenaten. She was depicted in the Amarna tomb of Huya twice.
It is also possible she was identical with another daughter of the royal couple, Nebetah, who ceases to be mentioned around the time when Beketaten appears[2].
Her only known title is King's Daughter of his Body. It is likely that she died at a young age; after Queen Tiye's death she is never mentioned again.
