Mykolaivka (Ukrainian: Миколаївка), previously Mykolaivka-Vyrivska (until 1957) and later Zhovtneve (1957–2016) is a rural settlement in Sumy Raion, Sumy Oblast, northeastern Ukraine.

[4] The settlement was called Zhovtneve, to commemorate the October Revolution, until 2016.

On 19 May 2016, Verkhovna Rada adopted decision to rename Chervone to Esman according to the law prohibiting names of Communist origin.

[5] Until 26 January 2024, Mykolaivka was designated urban-type settlement.

On this day, a new law entered into force which abolished this status, and Mykolaivka became a rural settlement.
