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. However, Foley and Ross could find no lexical or morphological evidence that they are related to the Sepik or Ramu languages.
Yuat languages distinguish inclusive and exclusive first person pronouns, a feature not found in most other Papuan languages. This tyopological feature has also diffused from Yuat into the Grass languages, which are spoken contiguously to the Yuat languages.
