Religion in Singapore is characterised by a wide variety of religious beliefs and practices due to its diverse ethnic mix of peoples originating from various countries. This means that Singapore is commonly termed as a "melting pot" of various religious practices originating from different religious denominations around the world. Most practised religious denominations are present in Singapore, with the Inter-Religious Organisation, Singapore (IRO) recognising 10 major religions in the city state. A 2014 analysis by the Pew Research Center found Singapore to be the world's most religiously diverse nation.
