Fataluku (also known as Dagaga, Dagoda', Dagada) is a Papuan language spoken by approximately 37,000 people of Fataluku ethnicity in the eastern areas of East Timor, especially around Lospalos.

[2] Fataluku's closest relative is Oirata,[3] spoken on Kisar island, in the Moluccas of Indonesia.

[4] Fataluku is given the status of a national language under the constitution.

[6] The differences that exist between these dialects, especially beyond phonology, are unclear and require more research.

Dialects differ with respect to the phonetic realization of palatal obstruents, the presence of a glottal stop phoneme and a voicing distinction in stops, as well as aspects of the stress system.
