Religion in Bangladesh

Sunni Islam is the largest religion in Bangladesh and in all of its districts, except Rangamati. Hinduism, Buddhism and Christianity are the other major religions in the country. A few people also follow other religions and denominations such as Shia Islam, Ahmadiyya, Sikhism, Bahai Faith, Jainism, Judaism, Zoroastrianism, Ravidassia (Ad-Dharmi) and Animism.

The United Nations categorizes Bangladesh as a moderate democratic Muslim country. The Constitution of Bangladesh refers to Islam twice: the document begins with the Islamic phrase Bismillahir Rahmanir Raheem (Arabic: بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ, lit. 'In the name of Allah, the Beneficent, the Merciful') and article (2A), added later, declares that: "Islam is the state religion of the republic". However, secularism is also one of the four fundamental principles of the Constitution of Bangladesh since 2011, and the country is mostly governed by secular laws dating from the British colonization. The Constitution guarantees freedom of religion and declares that "the State shall ensure equal status and equal right in the practice of the Hindu, Buddhist, Christian and other faiths and religions". In 2022, Freedom House rated Bangladesh's religious freedom as 2 out of 4.
