The freedom to practice religion is a guaranteed right under the Spanish Constitution. In practice, the government and the rest of Spanish society uphold this liberty. Although no official state religion exists, the government and taxpayers contribute to the Catholic Church. There have been no reports of religious prisoners or forced conversions to the US Department of State.

The 4 most prominent Spanish religions

1.    Catholicism

Around 67.4% of Spaniards identify as Roman Catholic Christians. Since the region was part of the Roman Empire, Christianity has had a significant presence in Spain. However, following an Arab invasion in 711 AD, Islam became the ruling force and the most widely practiced religion.


This pattern continued until 1492 AD, after years of religious conflict between Muslims and Christians. Catholicism has been the dominant religion in Spain since 1492 and continues to be so today.

Even though Catholics make up the vast majority of the population, 61% of self-identified Catholics report that they do not attend mass very often. In fact, only 14% of Catholics report attending mass every Sunday or multiple times per week.

Furthermore, the number of parish priests and nuns has decreased nationwide. In a 2008 survey of European values, only 3% of those polled said religion was one of their top three values. The Spanish population appears to be undergoing a generalized secularization, as is happening throughout Western Europe.

2.    Atheism

Atheists and Agnostics now account for 20% to 22% of the population. This trend towards irreligion is accompanied by economic and social progress, as well as increased scientific research and educational attainment.

Increasing levels of atheism and agnosticism are seen across Western Europe. It is higher in cities, where people have higher educational attainment and income levels.

3.    Minority religious groups

Islam, Judaism, Protestant Christianity, Baha’i, Hinduism, and Buddhism are among the minority religions in Spain, along with a few others. One of these religions is practiced by approximately 3% to 5% of the population. Because of the country’s economic growth, Spain has accepted many immigrants to help fill labor shortages.


Because of the increase in immigration, the types of religions practiced in the country have shifted, as have the languages spoken and traditional cultural practices. Both Protestant and Islamic followers have grown in recent years. Apart from this, there are several ways to learn Spanish easily, allowing people to master this beautiful language and hit the country for employment purposes.

4.    Islam

Although both Protestant Christianity and Islam have grown in popularity in Spain in recent years, Islam has grown at a much faster rate. As previously stated, this is due to large waves of immigrants entering the country.

The majority of these newcomers are from Morocco and other African countries. Moroccans were not required to obtain a residency visa to live and work in Spain during the 1980s, so they migrated in large numbers, bringing religion with them.

With approximately 1.9 million followers or roughly 4% of the population, Islam is now the second most widely practiced religion in Spain. Muslims in the country are more likely to practice their religion than Catholics actively. This could lead to a revival of religious participation in some areas of Spain.
