Khaba (also read as Hor-Khaba) was a pharaoh of Ancient Egypt, active during the 3rd dynasty of the Old Kingdom period. The exact time during which Khaba ruled is unknown but may have been around 2670 BC.
King Khaba is considered to be difficult to assess as a figure of ancient Egypt. His name is archaeologically well-attested by stone bowls and mud seal impressions. Khaba's reign is securely dated to the Third Dynasty. Because of the contradictions within Ramesside king lists and the lack of contemporary, festive inscriptions, his exact chronological position within the dynasty remains disputed. These problems originate in part from contradictory king lists, which were all compiled long after Khaba's death, especially during the Ramesside era. It is also a matter of debate as to where Khaba might have been buried. Many Egyptologists and archaeologists propose that an unfinished step pyramid at Zawyet el'Aryan, known as the Layer Pyramid, belongs to him. Others believe instead that his tomb is a large mastaba close to the Layer Pyramid, where numerous stone vessels bearing Khaba's serekh have been found.
