Iyhkernofret was an Ancient Egyptian treasurer of the Twelfth Dynasty, under king Senusret III. On his monuments he bears several important titles, including overseer of the double treasury, overseer of the double gold house, royal sealer and his main title treasurer. Iyhkernofret is known from several stelae found at Abydos. One of these stelae contains a biography. The stela is now in the Egyptian Museum of Berlin (Stela Berlin 1204). According to its text, Iyhkernofret grew up at the royal court. When he was 26, he became friend of the king, which was most likely a special honor. However, the text of the stela is of special importance as it reports the arrangement by Iyhkernofret of a festival for Osiris at Abydos.
Not much is known about the family of Iykhernofret. His mother was called Zatkhons, while his father is not mentioned on his monuments.
