List of cities in Mykolaiv Oblast

There are nine populated places in Mykolaiv Oblast, Ukraine, that have been officially granted city status (місто) by the Verkhovna Rada, the country's parliament. Settlements with more than 10,000 people are eligible for city status although the status is typically also granted to settlements of historical or regional importance. As of 1 January 2022, the largest city in the oblast was the regional capital Mykolaiv, which had an estimated population of 470,011 people, while the smallest city was Nova Odesa, with an estimated population of 11,510 people.

Following an administrative reform on 18 July 2020, the oblast's five cities of regional significance were abolished and merged into four new, expanded districts (raions). The four raions that make up the oblast are Bashtanka, Mykolaiv, Pervomaisk, and Voznesensk raion.
