Pervomaisk (Ukrainian: , Pervomajs'k) is a city in Mykolaiv Oblast, Ukraine and the administrative center of the Pervomaisk Raion. Administratively, the city is incorporated as a city of oblast significance and does not belong to the raion. It is located on the Southern Bug river which bisects the city. Population:  In 2001, population was 70,170.
The city was formed when three neighbouring settlements: the village of Holta () and the town of Bohopil () around a county city of Olviopol (?) were merged. The merger was adopted by the All-Ukrainian Central Executive Committee on June 6, 1919. These cities existed from 1773 and the first settlement in the area was mentioned as early as 1676.
In World War II, Pervomaisk was occupied by the Axis Powers in 1941 and was divided between German occupation authorities on the east bank (Bohopol and Olviopol) and the Romanian-occupied region of Transnistria to the west (Holta). Holta served as the center of the Golta jude? (district) of Transnistria. Pervomaisk had been more than 1/3 Jewish before the war but most were murdered during the occupation.
In Pervomaisk, there is at 48°4'0"N 30°51'29"E a 196 metres tall guyed TV mast, equipped with 6 crossbars running from the mast body to the guys.
Pervomaisk was the former location of the 46th Rocket Division of the 43rd Rocket Army of the Soviet Strategic Rocket Forces, formed during the Cold War. One of the commanders of the division, appointed in 1991, was General Major Mikhail Filatov. The RT-23UTTKh intercontinental ballistic missile silos based at Pervomaisk were destroyed, partially with Nunn-Lugar Cooperative Threat Reduction programme funding, during the 1990s.
