The Philippines stands as Asia's largest and most predominantly Christian nation, with an impressive 91.5% of its population identifying as Christian according to the 2020 national census, making it one of only two substantially Catholic countries in the Asian continent alongside Timor-Leste.
Roman Catholicism represents the dominant faith with approximately 79% of Filipinos—roughly 85.5 to 93 million adherents—belonging to the Catholic Church, positioning the archipelago as the world's third-largest Catholic population behind only Brazil with 123.4 million and Mexico with 100 million believers.
Christianity's deep roots in the Philippines trace back to Spanish colonization in the 16th century when missionaries arrived in Cebu bringing Catholic teachings that eventually spread throughout the islands, with Catholicism serving as the nation's state religion during the Spanish colonial period until American rule established separation of church and state.
Beyond Catholicism, Protestant denominations account for approximately 13% of Christians including groups such as Iglesia ni Cristo, Seventh-day Adventists, Philippine Independent Church, and various Pentecostal congregations, while the remaining population consists primarily of Muslims at 5.5%, with smaller Buddhist, Hindu, and indigenous religious communities.
The Catholic Church maintains profound influence on Philippine society, culture, and politics, with 76.7% of Southeast Asia's entire Catholic population concentrated in the Philippines according to Vatican statistics, solidifying the nation's unique status as Christianity's strongest bastion in Asia and ranking fifth globally among all Christian-majority countries with approximately 4% of the world's 2.3 billion Christians.
