The Jemdet Nasr Period is an archaeological culture in southern Mesopotamia (modern-day Iraq). It is generally dated from 3100–2900 BC. It is named after the type site Tell Jemdet Nasr, where the assemblage typical for this period was first recognized. Its geographical distribution is limited to south-central Iraq. The culture of the proto-historical Jemdet Nasr period is a local development out of the preceding Uruk period and continues into the Early Dynastic I period.
