The Dagoman are a group of Indigenous Australians living in the Northern Territory of Australia.
The Dagoman language was one of the non-Pama–Nyungan languages, closely related to its , Wardaman and Yangman. All three may be considered to be dialects of the one language isolate. The language is extinct, the last known speaker being Mrs Martha Hart of Pine Creek, who died in 1982. There is a considerable overlap of vocabulary and typological features with Wakiman
Dagoman country lay to the north of that of the Wardaman people, while its borders with those of the Jawoyn were at Kumbidgee by the water-hole of the rock bat (Wallan, in Jawoyn legend), along the old north-south road running from Maranboy to Katherine.
