Sabu (died c. 70 BCE) was a Medjay protector of Siwa. Born during the reign of Ptolemy XII Auletes, he was secretly one of the last in the bloodline of the Medjay, elite warriors who sworn to protect Egypt and its traditions. With his wife, Ahmose, he was the father of the Hidden One Bayek.
Sabu was killed in around 70 BCE by Bion who was ordered to eradicate the Medjay. Sabu managed to push Bayek to safety before meeting his fate. With his death, Bayek became the last living Medjay.
