By Editor It is a fact that right now, as of 2026, the most followed religion in the world is definitely Christianity, like there are as many as 2.5 billion followers out there. So no doubt, there are some nations around the globe where you can find christian population in the majority. And if you already feel somewhat intrigued about finding out more about all this, then just keep on reading this post on the 10 Highest Christian Population Countries in the World 2026.
1. United States
The United States takes the top spot on this list and for a very obvious reason.The country is home to the largest Christian population in the world, totalling more than 210 million followers. Even though the overall percentage of Christians has slightly dropped over the years, the absolute number still remains unmatched. Christianity in the US encompasses Catholics, Protestants, Orthodox Christians, and a number of other denominations. Due to its huge population size, there is no other country near the United States in terms of the total number of Christians.
2. Brazil
Brazil is the second largest country by number of Christians with more than 180 million believers. Christianity is deeply ingrained in Brazil’s culture and people’s way of life. Although the majority of Catholics has been the main religious group in the past, there has been a rapid increase of Evangelical and Protestant communities in the recent years. Because of its massive population and deeply religious nature, Brazil is a clear second place runner in this top. Though, looking at how fast their population is growing, you should not even be surprised to see them ranking first on this list in a matter of a few decades. That’s a real possibility we’re talking about.
3. Mexico
In third place is Mexico with approximately 125 million Christians. It has a long history of Christianity which has been largely influenced by Roman Catholicism. People still depend on and celebrate their faith through festivals, customs and daily life throughout the country. With its strong Christian heritage and large population, no wonder Mexico is in the top three countries in the world.
4. Russia
Number four on the list goes to Russia with about 105 million Christians. The majority of Christians in Russia are a part of the Eastern Orthodox Church, and the Church has a deep historical relationship with the country. While church attendance on a regular basis may be less compared to some countries, the strength of religious identity is still quite high. The fact that Russia has a large population is the main reason why it is ranked so high on this list.
5. Philippines
Coming in at number five is the Philippines, which is recognized as the largest Christian-majority country in Asia. With more than 95 million Christians, the country has a powerful Catholic influence that is reflected in the way of life, festivals, and national customs. Christianity is a key element of the Filipino culture, thus, achieving a top five position is certainly justified.
6. Nigeria
With more than 95 million Christians, Nigeria is ranked sixth in the world. The majority of the Christian population is found in the southern and central parts of the country. The Catholic and Protestant faiths have a strong presence in these areas. Owing to the fast-paced population growth in Nigeria, the Christian population is also growing in number every year. And as of right now, not a single doubt in the fact that when we talk about the Africa continent as a whole, Nigeria is the biggest christian nation there, and with the population growing year after year, it certainly will hold the spot for a long time.
7. Democratic Republic of the Congo
Coming in at number seven is the Democratic Republic of the Congo, with nearly 90 million Christians.

8. Ethiopia
With nearly 75 million Christians, Ethiopia ranks eighth. Ethiopia stands out as one of the oldest Christian nations in the world because of its long Christian history. The Ethiopian Orthodox Church is dominant, but the Protestant community is also increasing. Religion deeply shapes the culture and traditions of the country.
9. Italy
Italy ranks ninth in the list of countries with the most Christians, with an estimated 50 million Christians in the country. Italy is mostly known worldwide as the center of the Roman Catholic Church. Although attending church has become less frequent in recent years, most of the people still consider themselves Christians.

10. Germany
Germany comes in tenth on the list with almost 45 million Christians. The people are mostly split between the Catholic and Protestant denominations. Even though secularism has grown over the past few years, Germany’s huge population still guarantees it a spot among the top ten countries with the greatest Christian populace.
