Sithathoriunet (Egyptian: Sꜣt-Ḥwt-Ḥr-Jwnt, lit. 'daughter of Hathor of Dendera') was an ancient Egyptian sꜣt-nsw or 'king's daughter' of the Twelfth Dynasty, mainly known from her burial at El Lahun in which a treasure trove of jewellery was found. She was possibly a daughter of Senusret II since her burial site was found next to the pyramid of this king. This would make her one of five known children and one of three daughters of Senusret II, alongside Senusret III, Senusretseneb, Itakayt and Nofret. She bore the title king's wife, and was probably the wife of Senusret III.
Sithathoriunet was buried in the El Lahun pyramid complex. She must have died while Amenemhat III was pharaoh, since objects bearing his name were found in her tomb. Her name and titles survived on her canopic jars and on an alabaster vessel found in her tomb.The tomb was excavated in 1914 by Flinders Petrie and Guy Brunton. It had previously been robbed in antiquity but a niche in the burial site escaped the looters' attention. In this niche remains were found of several boxes filled with jewellery and cosmetic objects, such as razors, a mirror and vases. The discovered jewellery is considered to be among the highest quality ever found in an ancient Egyptian tomb. These finds included two pectorals, one with the praenomen of Senusret II, and the other with the name of Amenemhat III, a crown and bracelets inscribed with the praenomen of Amenemhat III. The majority of the objects are cloisonné gold inlaid with precious stones. The majority of the finds are located in the Metropolitan Museum of Art in New York, although the crown and the pectoral of Amenemhat III are in the Egyptian Museum in Cairo.
