Kyiv Oblast

Kyiv Oblast spans a total area of 28,100 km2 (10,849 sq mi), which is about 35 times larger than Kyiv city. The oblast is situated in north-central Ukraine, bordered by Zhytomyr Oblast to the west, Vinnytsia Oblast to the southwest, Cherkasy Oblast to the south, Poltava Oblast to the southeast, Chernihiv Oblast to the east and northeast, and Homyel Voblasts of Belarus to the north.

The Dnieper River (Dnipro) runs through the oblast, with a total length of 246 km (153 mi) within its boundaries. The region is characterized by numerous rivers, including tributaries such as Pripyat, Desna, Teteriv, Irpin, Ros, and Trubizh, as well as 13 reservoirs and approximately 750 small lakes.

Kyiv Oblast was established on 27 February 1932 as part of the Ukrainian Soviet Socialist Republic, making it one of the first five original oblasts in Ukraine. The territory has historical roots in the Kiev Voivodeship under the Polish–Lithuanian Commonwealth and the Kiev Governorate under the Russian Empire.

The current borders of the oblast were defined after the Chernobyl disaster in 1986, which led to the creation of the Chernobyl Exclusion Zone in the northern part of the oblast.

As of the 2001 Ukrainian census, ethnic Ukrainians comprised 92.5% of Kyiv Oblast's population, while ethnic Russians accounted for 6.0%. The estimated population, excluding Kyiv, was around 1.72 million in 2013, with a population density of 63.01/km2.

Ukrainian is the sole official language throughout the oblast, and a 2023 survey indicated that 68% of residents supported Ukrainian as the only state language in Ukraine. The Kyiv Oblast Council approved a program in March 2023 aimed at promoting the Ukrainian language in public life.

Kyiv Oblast's economy is diverse, with major industries including power production, food processing, chemical and petrochemical industries, and mechanical engineering. The oblast produces a significant share of national outputs, including 63% of tire production for automobiles and 53% of excavators.

On 24 February 2022, Kyiv Oblast was invaded by Russian Armed Forces as part of the broader invasion of Ukraine. A Ukrainian counter-offensive successfully liberated the region on 2 April 2022, although renewed attacks occurred shortly thereafter.

Kyiv Oblast is home to several notable cultural and historical sites, including the Pereiaslav museum of folk architecture and the Museum-villa of Kateryna Bilokur. These sites reflect the rich cultural heritage of the region and its significance within Ukraine.
