The Ubaid period (c. 5500–3700 BC)^[1] is a prehistoric period of Mesopotamia. The name derives from Tell al-'Ubaid where the earliest large excavation of Ubaid period material was conducted initially in 1919 by Henry Hall, Leonard Woolley in 1922-1923, and later by Pinhas Delougaz in 1937.^[2]^[3]^[4] Excavations continue into the present day.

In Southern Mesopotamia, this period marks the earliest known human settlements on the alluvial plain, although it is likely earlier periods exist that are obscured under the alluvium.^[5] In the south it has a very long duration between about 5500 and 3800 BC when it is replaced by the Uruk period.^[1]

In Northern Mesopotamia the period runs only between about 5300 and 4300 BC.^[1] It is preceded by the Halaf period and the Halaf-Ubaid Transitional period and succeeded by the Late Chalcolithic period.
