Nicobarese is an isolated group of six closely related Mon-Khmer languages spoken in the Nicobar Islands of India. They have a total of about 30,000 speakers (22,100 native). The majority of Nicobarese speakers use the Car language.

The morphological similarities between Nicobarese languages and Austronesian languages have been used to help support the Austric hypothesis.
