Voznesensk Raion (Ukrainian: Вознесенський район) is a raion (district) in Mykolaiv Oblast, Ukraine. Its administrative center is the town of Voznesensk. Population: 175,542 (2022 estimate).^[1]

In 1923, uyezds in Ukrainian Soviet Socialist Republic were abolished, and the governorates were divided into okruhas. In 1923, Voznesensk Raion with the administrative center located in Voznesensk was established. It belonged to Mykolaiv Okruha of Odessa Governorate.^[2] In 1925, the governorates were abolished, and okruhas were directly subordinated to Ukrainian SSR. In 1930, okruhas were abolished, and on 27 February 1932, Odessa Oblast was established, and Voznesensk Raion was included into Odessa Oblast. In 1944, Voznesensk Raion was transferred to Mykolaiv Oblast. In 1975, Voznesensk became the city of oblast significance.^[3]

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 Voznesensk Raion was significantly expanded. Four abolished raions, Bratske, Domanivka, Veselynove, and Yelanets Raions, as well as the cities of Voznesensk and Pivdennoukrainsk, which were previously incorporated as a city of oblast significance and did not belong to any raion, were merged into Voznesensk Raion.^[4][5] The January 2020 estimate of the raion population was 29,241 (2020 est.)^[6]
