Pervomaiske Raion (Ukrainian: Первомайський район, Russian: Первомайский район, Crimean Tatar: Curçı rayonı) was one of the twenty-five regions of the Autonomous Republic of Crimea, Ukraine until its abolition in 2020.

Russia, which has occupied the entire Crimean Peninsula since 2014, continues to use it as part of its administration, the Republic of Crimea.

The raion is named after its administrative center, the urban-type settlement of Pervomaiske.
