The Umbugarla language is an Australian language isolate once spoken by three people in Arnhem Land, northern Australia, in 1981, and is now extinct.
Umbugarla was once considered a language isolate (together with Ngurmbur as a dialect), but Mark Harvey has made a case for it being part of a family of Darwin Region languages.
