The Munda languages are a language family spoken by about nine million people in India and Bangladesh. Historically, they have been called the Kolarian languages. They constitute a branch of the Austroasiatic language family, which means they are related to languages such as Mon and Khmer languages and Vietnamese, as well as minority languages in Thailand and Laos and the minority Mangic languages of South China. The origins of the Munda languages are not known, but they predate the other languages of eastern India. Ho, Mundari, and Santali are notable languages of this group.
