The Trans-Fly–Bulaka River aka South-Central Papuan languages form a hypothetical family of Papuan languages. They include many of the languages west of the Fly River in southern Papua New Guinea into southern Indonesian West Papua, plus a pair of languages on the Bulaka River a hundred km further west.
The family was posited by Stephen Wurm as a branch of his 1975 Trans–New Guinea proposal. Wurm thought it likely that many of these languages would prove not to belong to Trans–New Guinea, but rather to have been heavily influenced by Trans–New Guinea languages. Malcolm Ross (2005) concurred, and removed most of them.
