Merneith was a consort and a regent of Ancient Egypt during the First Dynasty. She may have been a ruler of Egypt in her own right, based on several official records. If this was the case and the earlier royal wife Neithhotep never ruled as an independent regent, Merneith may have been the first female pharaoh and the earliest queen regnant in recorded history. Her rule occurred around 2950 BC for an undetermined period. Merneith’s name means "Beloved by Neith" and her stele contains symbols of that ancient Egyptian deity. She may have been Djer's daughter and was probably Djet's senior royal wife. The former meant that she would have been the great-granddaughter of unified Egypt's first pharaoh, Narmer. She was also the mother of Den, her successor.

The First Dynasty of ancient Egypt covers the first series of Egyptian kings to rule over a unified Egypt. It immediately follows the unification of Upper and Lower Egypt, possibly by Narmer, and marks the beginning of the Early Dynastic Period, when power was centered at Thinis.
