Zaporizhzhia Oblast (Ukrainian: Запорізька область, romanized: Zaporizka oblast), commonly referred to as Zaporizhzhia (Запоріжжя), is an oblast (region) in south-east Ukraine. Its administrative centre is the city of Zaporizhzhia. The oblast covers an area of 27,183 square kilometres (10,495 sq mi), and has a population of 1,638,462 (2022 estimate). The oblast is an important part of Ukraine's industry and agriculture.
Most of the oblast's area, including all of the coast, has been under Russian military occupation since the 2022 Russian invasion of Ukraine, although the capital and the majority of the population have remained under Ukrainian administration. In September 2022, Russia declared it had annexed the Zaporizhzhia oblast based on the results of a disputed referendum. The referendum and subsequent annexation are not internationally recognized.
