This article is about the Pharaoh, Unas. For the Stargate race, see Unas (Stargate).

Unas (also Wenis or Oenas) was a Pharaoh of Ancient Egypt, the last king of the Fifth dynasty. He built a small pyramid decorated with ancient texts -- the so-called Pyramid Texts . He was the first known to ever decorate his pyramid in this way. He probably had no sons, so the Fifth dynasty came to an end after his death. His successor, Teti, married his daughter, Iput , in order to legitimize his rule and found the 6th dynasty.
