Tadhukipa was a Mitanni princess who was sent to marry Amenhotep III (1391-1353 B.C.) of the 18th Dynasty, and who is believed by some to be Queen Kiya, the wife of Akhenaten. The niece of the Mianni princess Khirgipa, who had previously married Amenhotep, Tadhukipa was sent to Thebes either shortly before or after Amenhotep's death. She is mentioned in a letter from Queen Tiy as having been married to Akhenaten.
