Mutbenret (older reading "Benretmut") or Mutnodjmet was an Egyptian noblewoman, and said to be the sister of the King's Great Wife Nefertiti.
The reading of the name is disputed, as the hieroglyphs for "nedjem" (nḏm) and "bener" (bnr) are similar in appearance and both signify "sweet."
[2] Likely relevant, the name of Queen Tanodjmy is written with the "bener" sign followed by a phonetic complement m, indicating that the ostensible "bener" in that instance is to be read as "nedjem" and that the two signs may have functioned interchangeably in such names; the same might be true for Mutbenret/Mutnodjmet, in which case the latter form would be correct.
[4] Mutbenret/Mutnodjmet appears in a number of scenes at Amarna as a member of the royal court of Akhenaten and Nefertiti.
According to some scholars, Mutbenret/Mutnodjmet was the same person as Mutnodjmet, the wife of Horemheb, the last ruler of the Eighteenth Dynasty.
