Meritaten also spelled Merytaten or Meryetaten (14th century BC) was an ancient Egyptian queen of the eighteenth dynasty; who held the position of Great Royal Wife to Pharaoh Smenkhkare; who may have been a brother or son of Akhenaten. Her name means 'She who is beloved of Aten'; Aten being the sun-god her father worshipped; Meritaten also may have served as pharaoh in her own right under the name Ankhkheperure Neferneferuaten.

Meritaten was the first of six daughters born to Pharaoh Akhenaten and his Great Royal Wife; Nefertiti. Her sisters are Meketaten; Ankhesenpaaten; Neferneferuaten Tasherit; Neferneferure and Setepenre. She is known to have later married Pharaoh Smenkhare. There are no known children; but the young girls named Meritaten-tasherit and Ankhesenpaaten-tasherit are sometimes conjectured to be the daughters of Meritaten and Smenkhare.
