# List of endangered languages of Oceania

This is a list of endangered languages of Oceania, based on the definitions used by UNESCO.
An endangered language is a language that it is at risk of falling out of use because there is little transmission of the language to younger generations. If a language loses all of its native speakers, it becomes an extinct language.

## Australia
