Matbat is a heavily Papuan-influenced Austronesian language spoken in West Papua, Indonesia, on the island of Misool, Raja Ampat islands. Its dialects are Magey and Tomolol.: 17 Similar to the neighboring Ma'ya language, Matbat is one of a handful of Austronesian languages with true lexical tone rather than a pitch-accent system or complete lack of phonemic tonal contrasts as with most other Austronesian languages.
