According to Bulgaria's 2011 census, the main religion in Bulgaria is Orthodox Christianity. Around 59 percent of the country's 7.6 million inhabitants profess this faith.

Around 9.3 percent of the Bulgarian identify as atheist, and 7.8 percent follow Islam. A number of minority religions, including Judaism, Roman Catholicism, Armenian Apostolic Orthodox and Protestant Christianity make up about 2 percent of the population. Many of these minority religions live in well-defined geographic areas; for example, the country's Jewish community clusters in Sofia and along the Black Sea coast, while nearly all of the country's Roman Catholics live in Plovdiv. The question about religion in the Bulgarian census was optional; around 21.8 percent of the population simply did not answer.
