The 1st millennium in North American history provides a timeline of events occurring within the North American continent from 1 1000 CE in the Gregorian calendar. This time period is part of the Post-archaic period (Post-archaic stage), and 1 500 CE is known as the Middle Woodland Period, while 500 1000 CE is known as the Late Woodland Period in Eastern North America. Although this time line 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 the 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.
