Religion in Ukraine

Christianity is the predominant religion in Ukraine, with 85% of the population identifying as Christian according to a 2022 survey conducted by the Kyiv International Institute of Sociology (KIIS). Seventy-two percent of the population avowed fidelity to an Eastern Orthodox Church: 54% of Ukrainians proclaimed adherence to the autocephalous Orthodox Church of Ukraine; 14% identified as Orthodox Christian without specifying a church affiliation; 4% associated with the Moscow Patriarchate. Another 9% of Ukrainians professed devotion to the Catholic Church in Ukraine: 8% Ukrainian Greek Catholics and 1% Latin Catholics. Two percent of the population declared affiliation to a mainstream Protestant Church, and a further 2% identified with some alternative sect of Christianity.

Ten percent of Ukrainians identified as atheists. With Christianity in Ukraine overwhelmingly predominant, representative statistical samples of the population surveyed by KIIS in 2020, 2021, and 2022 reported 0% of respondents identifying with Judaism and Islam. An older survey by the Razumkov Center in 2018 estimated Jews in Ukraine at 0.4% of the population, with smaller 0.1% minorities following Hinduism, Buddhism and Paganism (Rodnovery). According to the surveys conducted by Razumkov in the 2000s and early 2010s, such proportions have remained relatively constant throughout the last decade, while the proportion of believers overall has decreased from 76% in 2014 to 70% in 2016 and 72% in 2018.

As of 2022, Christianity was particularly strong in westernmost Ukrainian regions, where most Greek Catholics lived. In central, southern and eastern regions, Christians constitute a smaller proportion of the total population, particularly low in the easternmost region of Donbas.
