Djedefre (also known as Radjedef) was an Egyptian pharaoh, the son and immediate successor of Khufu. The mother of Djedefre is unknown. His name means "Enduring like Re." Djedefre was the first king to use the title Son of Ra as part of his royal titulary, which is seen as an indication of the growing popularity of the cult of the solar god Ra.
He married his (half-) sister Hetepheres II, which may have been necessary to legitimise his claims to the throne if his mother was one of Khufu's lesser wives. He also had another wife, Khentetka with whom he had (at least) three sons, Setka, Baka and Hernet, and one daughter, Neferhetepes. These children are attested to by statuary fragments found in the ruined mortuary temple adjoining the pyramid. Various fragmentary statues of Khentetka were found in this ruler's mortuary temple at Abu Rawash. Abu Rawash actually sits at an elevation higher than the rest of Giza, making it the highest, albeit not the tallest, pyramid. Some historians claim that the "pyramid" at Abu Rawash isn't even a pyramid at all; instead, it may be a "sun temple." Archeaologist Vassil Dobrev has claimed that it may not even be Djedefre's. Excavations by the French team under Michel Valloggia have recently added another potential daughter, Hetepheres, as well as a son, Nikaudjedefre, to this list.
