The dominant religion in Costa Rica is Roman Catholicism, practiced by roughly 47% of the population, and Costa Rica remains one of the very few countries on Earth where Catholicism is the official state religion, written directly into the constitution. Yet the country is far from religiously uniform: a fast-growing Protestant minority, a sizeable share of religiously unaffiliated people, and small communities of other faiths together make up a more varied spiritual landscape than the official label suggests.
The Religious Breakdown Today
Surveys of religious affiliation in Costa Rica consistently produce a few clear groupings. While exact figures shift between polls, the general distribution looks like this:
- Roman Catholic: approximately 47% of the population, the single largest group and the constitutionally recognised faith.
- Protestant and Evangelical: roughly 19% and rising, dominated by Pentecostal and evangelical congregations.
- Religiously unaffiliated: around 17%, including agnostics, atheists, and those who believe but do not identify with a church.
- Other Christian denominations: about 5%, including groups such as Jehovah's Witnesses and Latter-day Saints.
- Other faiths and none specified: the remaining share, covering small Jewish, Buddhist, Baha'i, and indigenous spiritual communities.
The headline trend is a slow decline in Catholic majority alongside steady evangelical growth, a pattern repeated across much of Latin America. Even so, Catholic identity remains tightly bound to national culture, and many Costa Ricans who rarely attend Mass still describe themselves as Catholic.
Why Catholicism Is the State Religion
Spanish colonisers introduced Catholicism in the 16th century. Because the territory had a comparatively small indigenous population and limited mineral wealth, settlement was sparse and the faith spread quickly among the European farmers who came to dominate the central highlands. By independence in 1821, Catholicism was deeply embedded in everyday life.
The decisive legal step came with the Constitution of 1949, which named Roman Catholicism the official religion of the state while also guaranteeing freedom of worship for everyone else. That arrangement still stands, making Costa Rica an unusual case: the government funds certain church functions and Catholic clergy hold a formal status, yet other religions practise openly and without persecution. The same 1949 constitution famously abolished the national army, a peace-oriented decision often linked to the country's Catholic social outlook.

Faith Woven Into Daily Life
Religion in Costa Rica is most visible through tradition and celebration rather than rigid doctrine. The single largest religious event is the Romeria, an annual pilgrimage held in the days around August 2. Pilgrims walk, sometimes for days and from every corner of the country, to the Basilica of Our Lady of the Angels in Cartago. The event draws on the order of two million participants, an extraordinary figure in a nation of around five million people, and the most devout cover the final stretch on their knees.
Beyond the Romeria, the rhythm of the calendar is shaped by faith. Semana Santa (Holy Week) is a national holiday season when much of the country pauses. Christmas brings elaborate nativity scenes known as portales and the cooking of traditional tamales. Almost every town marks its own patron-saint festival, or fiesta patronal, blending religious processions with music, food, and bullriding-style entertainment. Meanwhile, evangelical churches have built a lively presence with energetic worship services and a growing voice in public debate.
Sacred Sites and Landmarks
The spiritual heart of the country is the Basilica of Our Lady of the Angels in Cartago, home to La Negrita ("the Black Virgin"), a small dark stone statue only about 20 centimetres tall that is the most venerated religious object in Costa Rica. Tradition holds that the figure repeatedly returned to the rock where it was first discovered, which is now enclosed within the basilica.
Other notable sites include the Metropolitan Cathedral in San Jose, the country's principal Catholic church; the colonial Orosi Church of 1743, often cited as the oldest church still in regular use; and the haunting ruins of the Parish of Santiago Apostol in Cartago, a stone shell left after repeated earthquakes. The Quaker community that helped establish the cloud-forest town of Monteverde is a reminder that smaller faith groups have also shaped the landscape, while several indigenous reserves continue to practise traditional spiritual customs.
Religion and Costa Rica's Progressive Streak
Costa Rica often sits at the more liberal end of Latin American politics, which sometimes places its laws in tension with conservative Catholic teaching. Debates over family law and personal rights have repeatedly pitted secular and evangelical voices against traditional Church positions, and evangelical leaders have become influential players in national elections. The result is a society that is at once visibly devout and increasingly pluralistic, where the relaxed national greeting Pura Vida coexists comfortably with centuries-old religious devotion.
Frequently Asked Questions
What is the official religion of Costa Rica?
Roman Catholicism is the official state religion, recognised in the 1949 constitution. This makes Costa Rica one of the few countries in the world to grant a single faith official status while still guaranteeing freedom of worship for all other religions.
Are most Costa Ricans Catholic?
Yes, Catholics remain the largest single group at roughly 47% of the population. However, Protestant and evangelical churches have grown to nearly a fifth of the population, and around 17% report no religious affiliation, so the Catholic share is no longer overwhelming.
What is the Romeria pilgrimage?
The Romeria is an annual pilgrimage to the Basilica of Our Lady of the Angels in Cartago, peaking on August 2. Up to around two million people walk to honour La Negrita, the country's patron-saint statue, making it the largest religious gathering in Costa Rica.
Is religious freedom protected in Costa Rica?
Yes. Although Catholicism holds official status, the constitution explicitly protects freedom of worship, and Protestant, Jewish, Buddhist, Baha'i, and indigenous communities all practise openly across the country.
