Trans–New Guinea (TNG) is an extensive family of Papuan languages spoken on the island of New Guinea and neighboring islands ‒ corresponding to the country Papua New Guinea as well as parts of Indonesia.
The Papuan languages are the non-Austronesian and non-Australian languages spoken on the western Pacific island of New Guinea in Indonesia and Papua New Guinea, as well as neighbouring islands, by around 4 million people. It is a strictly geographical grouping, and does not imply a genetic relationship. The concept of Papuan (non-Austronesian) speaking Melanesians as distinct from Austronesian-speaking Melanesians was first suggested and named by Sidney Herbert Ray in 1892.

The Yuat languages are an independent family of five Papuan languages spoken along the Yuat River in East Sepik Province, Papua New Guinea. They are an independent family in the classification of Malcolm Ross, but are included in Stephen Wurm's Sepik–Ramu proposal.
