Gemenefhorbak was an ancient Egyptian vizier who officiated during the 26th Dynasty, most likely under Psamtik I. His father was the vizier Iufaa.^[1]

Gemenefhorbak was the "Vizier of the North",^[2] meaning that he exercised his authority over Lower Egypt. He is mainly known from his meta-graywacke sarcophagus which is now in the Museo Egizio (Turin 2201); on it, the carving of a necklace with the goddess Maat is a sign of his judicial office.^[3] The sarcophagus is also carved with a chapter of the Book of the Dead, as well as Gemenefhorbak's numerous titles;^[4] here he is also provided with the rather unusual title of "Controller of the great courts" (Ḫrp ḥwwt wrwt).^[2]
