Kharkiv borders Luhansk Oblast to the east, Donetsk Oblast to the southeast, Dnipropetrovsk Oblast to the southwest, Poltava Oblast to the west, Sumy Oblast to the northwest and Russia's Belgorod Oblast to the north. Its area is 31,400 square kilometres (12,100 sq mi), or 5.2% of the total territory of Ukraine.

The oblast is the third-most populous of Ukraine, with a population of 2,598,961 in 2021, more than half (1.42 million) of whom live in the city of Kharkiv, the oblast's administrative center.

Most of Ukraine's oblasts are named after their capital cities, officially called "oblast centers" (Ukrainian: обласний центр, translit. oblasnyi tsentr). The name of each oblast is a relative adjective, formed by adding a feminine suffix to the name of respective center city: Kharkiv is the center of the Kharkivs’ka oblast’ (Kharkiv Oblast). Most oblasts are also sometimes referred to in a feminine noun form, following the convention of traditional regional place names, ending with the suffix "-shchyna", as is the case with the Kharkiv Oblast, Kharkivshchyna.

The oblast borders Russia (Belgorod Oblast) to the north, Luhansk Oblast to the east, Donetsk Oblast to the southeast, Dnipropetrovsk Oblast to the southwest, Poltava Oblast to the west and Sumy Oblast to the northwest.

The northern and central parts are part of historic Sloboda Ukraine, and the southern part is part of historic Zaporizhzhia.

During the Soviet administrative reform of 1923–1929, the Kharkov Governorate was abolished in 1925 leaving its five okruhas: Okhtyrka (originally Bohodukhiv), Izium, Kupiansk, Sumy, and Kharkiv. Introduced in the Soviet Union in 1923, a similar subdivisions existed in Ukraine back in 1918. In 1930 all okruhas were also abolished with raions becoming the first level of subdivision of Ukraine until 1932.

The modern Kharkiv Oblast was established on 27 February 1932. In the summer of 1932, some parts of the oblast were included in the newly created Donetsk Oblast originally centered in Artemivsk (later in Stalino). Then in the fall, some territories of the Kharkiv Oblast were used in the creation of Chernihiv Oblast. More territories became part of Poltava Oblast in fall of 1937 and Sumy Oblast in winter of 1939.

During the Holodomor the population of the Kharkiv Oblast together with Kyiv Oblast suffered the most. During World War II, it was the site or large Soviet massacres of Poles (Piatykhatky) and German massacres of Jews (Drobytsky Yar). The region saw major fighting during World War II in several Battles of Kharkov between 1941 and 1943.

During the 1991 referendum, 86.33% of votes in Kharkiv Oblast were in favor of the Declaration of Independence of Ukraine. A survey conducted in December 2014 by the Kyiv International Institute of Sociology found 4.2% of the oblast's population supported their region joining Russia, 71.5% did not support the idea, and the rest were undecided or did not respond.

Following the Euromaidan, there was pro-Russian unrest in the region, and central government buildings were taken over by separatists in a failed attempt to create a separatist 'Kharkov's People's Republic'. The region also became a very popular destination for refugees from the Russian-occupied Donetsk and Luhansk Oblast regions.

As part of the 2022 Russian invasion of Ukraine, the Russian military launched a major military offensive in the region, which resulted in the occupation of parts of the oblast. By late August, about one third of the territory of Kharkiv Oblast was occupied including Izium and Kupiansk. In July 2022, the Donetsk People's Republic signed a memorandum to "liberate Kharkiv from Ukraine".

In early September 2022, the Ukrainian military commenced a counteroffensive in the region. Several settlements in the region were recaptured from Russian control. By 10 September 2022, Ukraine had recaptured Kupiansk and Izium. On 11 September, Russia had retreated from many of the settlements it previously occupied in the oblast and the Russian Ministry of Defense announced a formal withdrawal of Russian forces from most of Kharkiv Oblast stating that an "operation to curtail and transfer troops" was underway." By 12 September 2022, as the Russian front lines in Kharkiv Oblast continued to collapse, Ukrainian forces had managed to push back to the northeastern border with Russia in some areas of the region. By 3 October 2022, Russian forces had almost completely withdrawn from Kharkiv Oblast. As of 2023, fighting continues in the easternmost parts of the oblast in the Battle of the Svatove–Kreminna line. In May 2024, Russia launched a renewed offensive in Kharkiv Oblast.
