Nubnefer ("beautiful gold") may have ruled Ancient Egypt during the second dynasty (the Early Dynastic Period). He is only attested by a few fragments of pottery found in Djoser's step pyramid which reference a building called "Menti-Ankh" ("Life may endure"). This building was established during the reign of Nynetjer, the third of the second dynasty kings and so it is thought the reign of Nubnefer must also have been during the early part of the second dynasty.
However, his name does not appear on any of the Kings lists, or any other documents or artefacts promptng some egyptologists to suggest that he was not a distinct ruler but rather that Nubnefer is the Nomen (birth name) of Raneb
