Ukrainian nationality law details the conditions by which a person holds nationality of Ukraine. The primary law governing these requirements is the law "On Citizenship of Ukraine", which came into force on 1 March 2001. In June 2025, Ukraine legalized multiple citizenship.
Any person born to at least one Ukrainian parent automatically receives Ukrainian citizenship at birth. Foreign nationals may naturalize after legally residing in the country for at least five years, demonstrating proficiency in the Ukrainian language, and renouncing any previous nationalities.
