Wambaya is a Non-Pama-Nyungan West Barkly Australian language of the Mirndi language group that is spoken in the Barkly Tableland of the Northern Territory, Australia. Wambaya and the other members of the West Barkly languages are somewhat unusual in that they are suffixing languages, unlike most Non-Pama-Nyungan languages which are prefixing. Rachel Nordlinger notes that the speech of the Wambaya, Gudanji and Binbinka people "are clearly dialects" of a single language, which she calls "McArthur", while Ngarnga is closely related but is "probably best considered a language of its own".
