What language do they speak in Bali?

The primary language spoken in Bali is Balinese, which is a Malayo-Polynesian language closely related to the Indonesian language (Bahasa Indonesia). Many Balinese people also speak Indonesian fluently, as it is the official language of Indonesia and is used for communication in government, education, and business settings.

In addition to Balinese and Indonesian, English is widely spoken and understood in tourist areas and among those working in the hospitality and tourism industry. English is often used for communication with tourists, especially in hotels, restaurants, tour companies, and other tourist services. Learning a few basic phrases in Balinese or Indonesian can be helpful and appreciated when interacting with locals, but English is generally sufficient for most travelers in Bali.
