The majority and state religion of Iran is Shia Islam.
Religious minorities include:
- Sunni Islam (10% of the population)
- Christianity
- Zoroastrianism
- Jews
- Ahl-e Haqq
- Mandaeanss
- Bahai
Conversion from Islam to any of these religions is considered apostasy and can under the current government result in harassment and religious persecution.
Many Sufi sects are active within Iran. Examples are Sheykhi centred around Kerman and Naqshbandi mostly in the Azeri regions of Iran. They are considered muslims by the government.
