The northern Ukraine campaign was a theater of operation in the Russian invasion of Ukraine. It involved attacks by Russia across the Russo-Ukrainian and Belarusian–Ukrainian borders, beginning on 24 February 2022, for control of Kyiv, the capital of Ukraine, and the surrounding areas of Kyiv Oblast and northern regions Zhytomyr Oblast, Sumy Oblast, and Chernihiv Oblast. Kyiv is the seat of the Ukrainian government and the headquarters of the Armed Forces of Ukraine.

On 24 February 2022, Russia invaded Ukraine in an escalation of the Russo-Ukrainian War that started in 2014. The invasion became the largest attack on a European country since World War II. It is estimated to have caused tens of thousands of Ukrainian civilian casualties and hundreds of thousands of military casualties. By June 2022, Russian troops occupied about 20% of Ukrainian territory. From a population of 41 million in January 2022, about 8 million Ukrainians had been internally displaced and more than 8.2 million had fled the country by April 2023, creating Europe's largest refugee crisis since World War II. Extensive environmental damage caused by the war, widely described as an ecocide, contributed to food crises worldwide.
