Mykolaiv Raion (Ukrainian: Миколаївський район, romanized: Mykolaivskyi raion) is a raion (district) in Mykolaiv Oblast, Ukraine with a pre-war population of 636,832 (2022 estimate). Its administrative center is the city of Mykolaiv.

History

In the 19th century, the area belonged to Kherson Governorate. After the Russian Revolution, the area underwent a series of administrative changes. In December 1920, it was renamed Nikolayev Governorate, and in 1921 it was merged into Odesa Governorate. In 1923, governorates were abolished in the Ukrainian Soviet Socialist Republic. As a result, Mykolaiv Raion of Mykolaiv Okruha was established, with the administrative center in Mykolaiv, which belonged to the raion. In 1925, governorates were abolished, and okruhas were directly subordinated to the Ukrainian SSR. In 1930, okruhas were abolished, including Mykolaiv Raion. Instead the area was transferred to Varvarivka Raion. On 27 February 1932, the area was transferred to the newly created Odesa Oblast. On 22 September 1937, Mykolaiv Oblast was established on lands which previously belonged to Dnipropetrovsk and Odesa Oblasts, and Varvarivka Raion became part of newly created Mykolaiv Oblast. On 8 August 1945, Shyrokolanivka Raion was established on the area which previously belonged to Varvarivka and Tylihulo-Berezanka Raions. The area thus became split between Varvarivka and Shyrokyi Lan Raions. On 7 June 1957, Shyrokyi Lan Raion was abolished, and split between Varvarivka and Veselynove Raions. In January 1963, Varvarivka Raion was abolished, and Mykolaiv Raion was re-established.

On 18 July 2020, as part of the administrative reform of Ukraine, the number of raions of Mykolaiv Oblast was reduced to four, and the area of Mykolaiv Raion was significantly expanded. Four abolished raions, Berezanka, Nova Odesa, Ochakiv, and Vitovka Raions, as well as the cities of Mykolaiv and Ochakiv, which were previously incorporated as a city of oblast significance and did not belong to any raion, were merged into Mykolaiv Raion. In 2001, population of the district was 34,675. The January 2020 estimate of the raion population was 29,389 (2020 est.)
