Raneb or Nebra was a pharaoh of the 2nd Dynasty of Ancient Egypt. The ancient Greek historian Manetho suggests that Raneb's reign lasted 39 years, but Egyptologists question Manetho's view as a misinterpretation or exaggeration of information that was available to him. They credit Raneb with either a 10- or 14-year rule. According to different authors, Nebra ruled Egypt c. 2850 BCE.
