East Kazakhstan Region is a region of Kazakhstan. It occupies the easternmost part of Kazakhstan, and includes parts of the Irtysh River, Lake Markakol, and Lake Zaysan. Its administrative center is Oskemen. The region borders Russia in the north and northeast and the People's Republic of China, via Xinjiang, in the south and southeast. The easternmost point of the Oblast is within about 50 kilometres of the westernmost tip of Mongolia; however, Kazakhstan and Mongolia do not share a common border, the two countries being separated by a small part of Russia and China.
The region was created by the merger of two Soviet-era Kazakhstan oblasts: the old Vostochno-Kazakhstanskaya Oblast and Semipalatinsk Oblast. On 17 March 2022, it was announced that East Kazakhstan region would be divided, creating the Abai Region.
