Pervomaiske is a Ukrainian toponym. Places with the name include:
The toponym literally means "the first of May", in reference to the International Workers' Day holiday that takes place on that date. It shares the same etymology with the toponyms, Pershotravensk, and Pershe Travnia, among others. Due to the law "On the Condemnation and Prohibition of Propaganda of Russian Imperial Policy in Ukraine and the Decolonization of Toponymy", signed in April 2023 by Ukrainian president Volodymyr Zelenskyy, all localities in Ukraine with the name "Pervomaiske" or other May Day-related toponyms are set to be renamed by 27 January 2024. The Ukrainian Institute of National Memory has described toponyms related to May Day as "a clear example of massive Soviet ideological toponymic nomination aimed at glorifying the proletariat as the hegemon of the class struggle, the driving force of the October Revolution of 1917 and the future 'world revolution.'"[1]
