Freedom of religion in Algeria is regulated by the Algerian Constitution, which declares Islam to be the state religion (Article 2) but also declares that "freedom of creed and opinion is inviolable" (Article 36); it prohibits discrimination, Article 29 states "All citizens are equal before the law. No discrimination shall prevail because of birth, race, sex, opinion or any other personal or social condition or circumstance". In practice, the government generally respects this, with some limited exceptions.
