What Is the Main Religion in Portugal?

The main religion of Portugal is Roman Catholicism. According to the U.S. Department of State, more than 80 percent of Portugal's population of 10.6 million identify as Roman Catholic.

A large percentage of the country's Roman Catholics, however, do not take part in religious services on a regular basis. Other religions make up around 5 percent of the population. This group includes other Christian denominations, such as 250,000 evangelicals and 200,000 Eastern Orthodox believers, most of whom are immigrants from Ukraine. There are also tiny communities of Jews, Taoists, Zoroastrians, Hindus, Muslims and Buddhists.
