Indonesia is a diverse country with a rich cultural heritage that is reflected in its diverse religious landscape. The main religion of Indonesia is Islam, with over 85% of the population identifying as Muslim. Indonesia has the largest Muslim population in the world, making it a predominantly Islamic country.

However, Islam is not the only religion practiced in Indonesia. According to the most recent data, there are also significant populations of other religious groups, including Buddhism, Christianity, Hinduism, and Confucianism. These religious communities contribute to the vibrant tapestry of Indonesia's religious life.

While Islam is the main religion of Indonesia, the country is known for its religious diversity and tolerance. The Indonesian government officially recognizes six religions – Islam, Protestantism, Catholicism, Hinduism, Buddhism, and Confucianism – and guarantees freedom of religion to all its citizens.

Despite this official recognition of religious freedom, there have been reports of discrimination and violence against religious minorities in Indonesia. The government has taken steps to address these issues and promote religious harmony, but challenges remain in ensuring the full protection of religious freedom for all Indonesians.

Overall, the main religion of Indonesia is Islam, but the country also has a diverse religious landscape that includes significant populations of other religious groups. Indonesia is known for its religious diversity and tolerance, but challenges remain in ensuring the full protection of religious freedom for all its citizens.
