Irreligion in Croatia pertains to atheism, agnosticism, and lack of religious affiliation in Croatia. Even though the 2011 census showed that only 4.57% of Croats considered themselves irreligious, Gallup polls conducted in 2007 and 2008 found that 30.5% of respondents did not consider religion important in their lives. The Japanese research center, Dentsu, conducted a survey in 2006 concluding that 13.2% of Croats declare themselves irreligious, compared to the 7% found by a 2010 Eurobarometer survey across Europe.^[1][2]

Evidence suggests irreligion is the fastest growing religious status in Croatia.^[3] The number of agnostics and skeptics rose by more than 20 times in the last ten years, while the number of atheists almost doubled. The increase in agnosticism is also attributed to public figures declaring themselves agnostic, such as President Ivo Josipović.^[4] Several irreligious organizations were founded in the 2000s, such as Protagora, David, Glas razuma - Pokret za sekularnu Hrvatsku, Nisam vjernik. They organized public actions such as the "Conference of reason" and campaign "Without a god, without a master".^[5]
