The Huon languages are a language family, spoken on the Huon Peninsula of Papua New Guinea, that was classified within the original Trans–New Guinea (TNG) proposal, and William A. Foley considers their TNG identity to be established.
They share with the Finisterre languages a small closed class of verbs taking pronominal object prefixes some of which are cognate across both families (Suter 2012), strong morphological evidence that they are related.
Huon and Finisterre, and the connection between them, were identified by Kenneth McElhanon (1967, 1970).
Huon contains two clear branches, Eastern and Western.
The Western languages allow more consonants in syllable-final position (p, t, k, m, n, ŋ), while the Eastern languages have neutralized those distinctions to two, the glottal stop (written c) and the velar nasal (McElhanon 1974: 17).
