The dingiso (/dɪŋˈɡiːzoʊ/) (Dendrolagus mbaiso), also known as the bondegezou or bakaga, is an endangered, long-tailed marsupial found only in mountain forests on the west of the island of New Guinea (in Indonesia).

[2] Dr Tim Flannery and his team gave the species name mbaiso which means "the forbidden animal" in Moni, because of the local belief that dingiso is the spirit of their ancestors.

The species was first filmed for an episode of the BBC documentary South Pacific TV series in 2009, after 11 days of searching with local Moni tribesmen.

According to the IUCN Red List of Threatened Species, the dingiso inhabits mossy forests and shrubland and is "found in rugged areas".

Julie Boswell lists "hunting for food, habitat loss, increasing human populations, agricultural stresses, and climate change" as the main threats that the dingiso faces.
