With an area of 118,600 square kilometers, it is the second-smallest region in Kazakhstan (Turkistan Region is the smallest). It borders Russia (Astrakhan Oblast) to the west, as well as the fellow Kazakh regions Aktobe to the east, Mangystau to the south, and the West Kazakhstan Region to the north. The Ural River is the border between Asia and Europe and flows from Russia to the Caspian Sea through the region, meaning western Atyrau Region lies in Europe.
A large part of the region is situated in the oil-rich Caspian Depression. Many oil wells have been drilled in the Tengiz Field and Kashagan Field areas. An oil pipeline runs from Atyrau to Samara, Russia, where it joins the Russian pipeline system. A separate oil pipeline runs from the Tengiz field to the Russian Black Sea port of Novorossiisk.
Atyrau is traversed by the northeasterly line of equal latitude and longitude.
As of 2021, the Atyrau Region has a population of 659,074.
