Nefertari was a queen of the Eighteenth dynasty of Egypt, the first Great Royal Wife of Pharaoh Thutmose IV.

Her origins are unknown, it is likely that she was a commoner. On several depictions she and Queen Mother Tiaa are depicted as goddesses accompanying Thutmose. In the 7th year the new Great Royal Wife was Thutmose's sister Iaret; Nefertari either died or was pushed into the background when Iaret was old enough to become Thutmose's wife.

She was depicted together with her husband before gods in Gizeh, on eight stelae. She was also shown on a stela found in the Luxor Temple and was mentioned on a scarab found in Gurob. It is not known whether any children were born either to Nefertari or to Iaret; after Thutmose's death the next pharaoh was Amenhotep III, the son of a secondary wife called Mutemwia.
