Sobekneferu (sometimes written as Nefrusobek) was the Egyptian female pharaoh of the Twelfth Dynasty. Her name meant "the beauties of Sobek". Some scholars believe that she was the daughter of Pharaoh Amenemhat III and Manetho states that she was the sister of Amenemhat IV. She is the first female ruler of Egypt to have all her names and titles preserved, but Nitocris may have ruled in the Sixth Dynasty.
