Balinese is a Malayo-Polynesian language spoken on the Indonesian island of Bali, as well as Northern Nusa Penida, Western Lombok, Eastern Java, Southern Sumatra, and Sulawesi. Most Balinese speakers also use Indonesian. The 2000 national census recorded 3.3 million people speakers of Balinese, however the Bali Cultural Agency estimated in 2011 that the number of people still using the Balinese language in their daily lives is under 1 million. The language has been classified as "not endangered" by Glottolog.

Bali is a province of Indonesia and the westernmost of the Lesser Sunda Islands. East of Java and west of Lombok, the province includes the island of Bali and a few smaller offshore islands, notably Nusa Penida, Nusa Lembongan, and Nusa Ceningan to the southeast. The provincial capital, Denpasar, is the most populous city in the Lesser Sunda Islands and the second-largest, after Makassar, in Eastern Indonesia. The upland town of Ubud in Greater Denpasar is considered Bali's cultural centre. The province is Indonesia's main tourist destination, with a significant rise in tourism since the 1980s, and becoming an Indonesian area of overtourism. Tourism-related business makes up 80% of the Bali economy.
