3rd millennium BC in North American history

The 3rd millennium BC in North American history provides a timeline of events occurring within the North American continent from 3000 BC through 2001 BC in the Gregorian calendar. This time period (from 3000 BC to 2001 BC) is known as the Late Archaic. Although this timeline segment may include some European or other world events that profoundly influenced later American life, it focuses on developments within Native American communities. The archaeological records supplements indigenous recorded and oral history.

Because of potential inaccuracies inherent in radiocarbon dating and in interpreting other elements of the archaeological record, most dates in this timeline represent approximations that may vary a century or more from source to source. The assumptions implicit in archaeological dating methods also may yield a general bias in the dating in this timeline.
