The Balinese are an Austronesian ethnic group native to the Indonesian island of Bali and the surrounding islands. The Balinese population of 4.2 million live mostly on the island of Bali, making up 85% of the island's population. The Balinese are distinctive amongst the ethnic groups of Indonesia for their adherence to Balinese Hinduism rather than Abrahamic religions such as Islam or Christianity.
