Unas (also Oenas, Unis, Wenis, or Ounas) is a Pharaoh of Ancient Egypt, and the last ruler of the Fifth dynasty from the Old Kingdom.
His reign has been dated as falling between 2375 BCE and 2345 BCE.
Unas is believed to have had two queens, Nebet and Khenut, based on their burials near his tomb.
With his death, the Fifth dynasty came to an end, according to Manetho; he probably had no sons.
Furthermore, the Turin King List inserts a break at this point, which "gives us some food for thought," writes Jaromir Malek, "because the criterion for such divisions in the Turin Canon invariably was the change of location of the capital and royal residence."
However, there are several instances of uninterrupted continuity between the Fifth and the sixth dynasties: Kagemni, the vizer of Unas's successor Teti, began his career under Djedkare Isesi and Unas.
Teti's queen, Iput, is believed to have been the daughter of Unas, which shows Teti, Nicolas Grimal argues, "made no conscious break with the preceding dynasty."
Jimmy Dunn adds that "a pink granite gateway in Unas' mortuary temple bears the inscription of the names and titles of Teti, indicating that part of the temple was completed after Unas's death."
The break between the two dynasties may have been more as an official act than in fact.
The causeway of Unas's pyramid complex includes a bas relief showing how they transported a palm column by boat on the Nile.
