Religion

Argentina has been overwhelmingly Christian for much of its history, up to and including the present day. Roman Catholicism is the country's largest Christian denomination. This historical context owes a great deal to the Spanish influence brought about by newly conquered territories. However, throughout the twentieth century, immigration brought other Catholics and denominations from various regions to Argentina. The country has the largest Muslim and Jewish communities in Latin America, with the latter being the world's seventh most populous. Argentina is a member of the International Alliance for Holocaust Remembrance.

According to a 2005 survey, 24% of people regularly attend religious services, while 10.3% are unaffiliated. According to a 2015 Pew Research Center survey, only 35% of Argentines consider religion to be very important in their lives. As of 2019, 79.6% of Argentina's population is Christian, 62.9% are Roman Catholics, 15.3% are Evangelicals, 1.4% are other Christians, 18.9% are unaffiliated, and 1.2% belong to other religions. According to a 2018 Pew Research Center report, 37% of Argentines believe religion is not very or not at all important in their lives. This figure has been consistently higher than 30% since at least 2007.
