What are the Religions in Tonga?

Tonga is an extremely religious country, with around 99% of the population practising some form of Christianity. Christianity was introduced to the islands some 230 years ago and has been going strong since with Christian-related laws such as observing Sunday as a “day of rest”, for instance. Religion is also engrossed in the culture, with Tongans go to church services every Sunday. Nevertheless, Tonga is a country of religious freedom with a tiny proportion of the population identifying with other or no religions. Learn more about the religions in Tonga in the guide below.

Their influence in Tonga wasn’t solidified until the conversion of an influential chief, Taufa’ahau, who was then baptised in 1831 with the Christian name George Tupou and became King George Tupou I. The king influenced the conversion to Christianity across the nation. And the rest they say, is history…
