The Engan languages, or more precisely Enga–Kewa–Huli or Enga – Southern Highland, are a small family of Papuan languages of the highlands of Papua New Guinea.

The two branches of the family are rather distantly related, but were connected by Franklin and Voorhoeve (1973).

The languages fall into three quite distinct branches: Engan proper, Huli, and Southern Highlands: The Engan family constitutes a branch of the Trans–New Guinea languages in the classifications of Wurm and of Malcolm Ross, but the evidence for this is weak.

Usher links the Engan and Chimbu languages in a Central New Guinea Highlands family.

Ross (2005) has the following for the singular, Wiru has been added for comparison: Usher (2020) has not yet published reconstruction of Engan as a whole, but has done Engan proper:[4] Some lexical reconstructions of Proto-Trans Enga (Proto-Engan) by Usher (2020) are:[3] The Enga-Kewa-Huli reflexes of proto-Trans-New Guinea (pTNG) etyma, if Engan languages are indeed members of the Trans-New Guinea family, are:[5] Enga: Huli: Kewa: Mendi: Basic vocabulary of Enga and Kewa from William A.
