Through Nazi Germany

Important cities in Luhansk Oblast include Alchevsk, Antratsyt, Brianka, Kadiivka, Kirovsk, Krasnodon, Khrustalnyi, Luhansk, Lysychansk, Pervomaisk, Rovenky, Rubizhne, Sievierodonetsk and Sverdlovsk. All of the oblast is in the Donbas region.

In 2014, large parts of the oblast, including the capital Luhansk, came under the control of Russian-backed separatists who declared the Luhansk People's Republic, leading to a war against Ukrainian government forces. Since the 2022 Russian invasion of Ukraine, the oblast has come almost entirely under Russian occupation and has been the scene of heavy fighting, which continues in some places. In late September 2022, Russia declared the annexation of the entire oblast, along with three others, though the annexation remains internationally unrecognized. Russian-backed officials claimed in July 2025 that Russian forces had captured the last Ukrainian-held areas in Luhansk Oblast, bringing the entire region under their control. They made the same claim in April 2026, though Ukraine denied it.

Geography

Luhansk Oblast is in far eastern Ukraine. Its north–south length is 250 km, and east–west width 190 km. It covers an area of 26,700 km2, 4.42% of the total area of Ukraine.

The oblast has the longest segment of Ukraine's international border with Russia among other regions (see State Border of Ukraine), consisting of 746 km (464 mi). The abutting Russian oblasts are Belgorod Oblast to the north, Voronezh Oblast to the northeast, Rostov Oblast to the east. Abutting Ukrainian oblasts are Kharkiv Oblast to the west, and Donetsk Oblast to the south.

The region is located in the valley of the Siversky Donets river, which flows west to east through the oblast and splits it approximately in half. The southern portion of the region is elevated by the Donetsk Ridge, which is close to the southern border. The highest point is Mohyla Mechetna (367 m (1,204 ft)), the highest point of Donetsk Ridge. The left bank of the Siversky Donets is part of the Starobilsk Plain. To the north this transforms into the Central Russian Upland.
