|Pharaoh of Egypt|
|Successor||Neferkara I? or Netjerkare?|
Nitocris (Greek: Νίτωκρις) has been claimed to have been the last pharaoh of the Sixth Dynasty. Her name is found in the Histories of Herodotus and writings of Manetho but her historicity is questionable. She might have been an interregnum queen. If she is in fact a historical person, then she may be the sister of Merenre Nemtyemsaf II and the daughter of Pepi II and Queen Neith.
Ancient records 
According to Herodotus (Histories ii-100), she invited the murderers of her brother, the "king of Egypt", to a banquet, then killed them by flooding the sealed room with the Nile.
- ...[Nitocris] succeeded her brother. He had been the king of Egypt, and he had been put to death by his subjects, who then placed her upon the throne. Determined to avenge his death, she devised a cunning schema by which she destroyed a vast number of Egyptians. She constructed a spacious underground chamber and, on pretense of inaugurating it, threw a banquet, inviting all those whom she knew to have been responsible for the murder of her brother. Suddenly as they were feasting, she let the river in upon them by means of a large, secret duct. (Herodotus)
Then, to avoid the other conspirators, she committed suicide (possibly by running into a burning room). Manetho claims she built the "third pyramid" at Giza, which is attributed by modern historians and archaeologists to Menkaure. Manetho was most likely confused by the similarity of the names Menkaura (the prenomen or "throne name" of Nitocris) and Menkaure. Herodotus also has a Babylonian queen of the same name and talks of her constructions in Babylon, mainly connected with diverting the Euphrates. His story about her tomb and the inscription on it which fooled Darius into opening it, only to have another inscription on the inside that chastised the opener for being so greedy is an early example of a familiar cultural meme.
Nitocris is not mentioned, however, in any native Egyptian inscriptions and "she" probably did not exist. It was long claimed that Nitocris appears on a fragment of the Turin King List, dated to the Nineteenth Dynasty, under the Egyptian name of Nitiqreti (nt-ỉqrtỉ). The fragment where this name appears was thought to belong to the Sixth Dynasty portion of the king list, thus appearing to confirm both Herodotus and Manetho. However, microscopic analysis of the Turin King List suggests the fragment was misplaced in reassembling the fragmentary text, and that the name Nitiqreti is in fact a faulty transcription of the praenomen of a clearly male king Netjerkare Siptah I,  who is named on the Abydos King List as the successor of the Sixth Dynasty king Nemtyemsaf II. On the Abydos King List, Netjerkare Siptah is placed in the equivalent spot that Neitiqreti Siptah holds on the Turin King List.
In fiction 
- Two letters in the name are transposed in Bolesław Prus' 1895 historical novel Pharaoh, where "Nikotris" appears as the mother of the protagonist, Pharaoh "Ramses XIII" (there were only eleven Ramesside pharaohs).
- The Queen's Enemies, a play by Lord Dunsany, is based upon Herodotus' account of Nitocris' murderous activities.
- Nitocris is mentioned in two stories by H. P. Lovecraft, "The Outsider" and "Imprisoned with the Pharaohs". She is mentioned only in passing and portrayed as an evil queen reigning over ghouls and other horrors.
- Tennessee Williams' first published work is the 1928 short story "The Vengeance of Nitocris", detailing the queen's careful plan for revenge. She makes the people who slew her brother die in a fitting way.
- Le Basalte Bleu, a book by John Knittel, has a sort of time-travel plot in which the main character falls in love with the ancient queen. Knittel speculates that the origin of the Cinderella fairy tale lies in the marriage of Nitocris, who lost her golden sandal only to have it later found by the pharaoh.
- Nitocris La Dame de Memphis is a book by Pierre Montlaur.
- "The Mirror of Nitocris," a short story by Brian Lumley, features a mirror that once belonged to Nitocris which unleashes evil forces upon its owners.
- Nitocris is Queen to Merenra II in the novel Rhodopis of Nubia by Nobel laureate Naguib Mahfouz which tells the fateful love story of Pharaoh Merenra II (successor to Pepi II Six Dynasty) and the courtesan Rhodopis.
- Karl Sanders has a song called "Slavery Unto Nitokris" on his second solo album, Saurian Exorcisms.
