Prehistoric Egypt and Predynastic Egypt was the period of time starting at the first human occupation of the region and ending at the First Dynasty of Egypt around 3100 BC.
At the end of prehistory, "Predynastic Egypt" is traditionally defined as the period from the final part of the Neolithic period beginning c. 6210 BC to the end of the Naqada III period c. 3000 BC. The dates of the Predynastic period were first defined before widespread archaeological excavation of Egypt took place, and recent finds indicating a very gradual Predynastic development have led to controversy over when exactly the Predynastic period ended. Thus, various terms such as "Protodynastic period", "Zero Dynasty" or "Dynasty 0" are used to name the part of the period which might be characterized as Predynastic by some and Early Dynastic by others.
