Aktau (Kazakh: Ақтау, Aqtay') is a city in Kazakhstan, located on the east bank of the Caspian Sea. Its current name means "white mountain" in Kazakh, which may be due to its cliffs that overlook the Caspian. From 1964 to 1991 city was known as Shevchenko (Russian: Шевченко, Kazakh: S'evc'enko). Its former name was given due to the eponymous Ukrainian poet's period of exile in the area. It is located on the Mangyshlak Peninsula and is the capital of Mangystau Region.
