The Muthi Muthi people are an indigenous Australian people whose traditional lands are located in the Northern Riverina and Far West regions of New South Wales.

[2] The subgroup includes the related Watiwati Letjiletji languages.

[3] What is distinctive about it compared to the languages spoken by most contiguous peoples is that it lacks monosyllabic nouns.
