Nitocris (Greek: Νίτωκρις) possibly was the last queen of the Sixth Dynasty of Ancient Egypt.

Modern historians and archaeologists attribute that pyramid to a king of the Fourth Dynasty, Menkaure.

According to Herodotus (Histories ii-100), Nitocris invited the murderers of her brother, the "king of Egypt", to a banquet, then killed them by flooding the sealed room with the waters of the Nile.

Herodotus also indicated that, to avoid the other conspirators, she committed suicide (possibly by running into a burning room).

The name, Nitocris, is not mentioned in any known native Egyptian inscriptions in stone and it was long thought that this king appears under her Egyptian name of Nitiqreti (nt-ỉqrtỉ) on a fragment of the Turin King List, dated to the Nineteenth Dynasty.
