Pepi I Meryre (reigned 2332 – 2283 BC) was the third king of the Sixth dynasty of Egypt. His first throne name was Neferdjahor which the king later altered to Meryre meaning "beloved of Rê."
Pepi was the son of Teti and Iput, who was a daughter of Unas, last pharaoh of the previous dynasty. He needed the support of powerful individuals in Upper Egypt in order to put down his brother, the usurper Userkare who had murdered his father and for Pepi to win back his rightful throne. These individuals would remain a strong presence in his court thereafter.
His two most important wives and the mothers of his two successors (Merenre Nemtyemsaf I and Pepi II) were Ankhesenpepi I and Ankhesenpepi II. Other known wives include Meritites IV, Nubwenet and Inenek-Inti, who are buried in pyramids adjacent to that of Pepi, Mehaa, who is named in the tomb of her son Hornetjerkhet, and a queen named Nedjeftet who is mentioned on relief fragments. He also had a son called Teti-ankh and two daughters, Iput II and Neith, both became wives to Pepi II.
The Egyptian noble Meryra (also Merire) was the only certain High Priest of the Aten, amongst his other titles were Hereditary Noble and High Official and Fan-bearer on the Right Side of the King, which emphasise his closeness to the king.
He had a tomb constructed at Amarna, Tomb 4, although his remains have never been identified. (See Tombs of the Nobles.)
