The Awyu–Ok languages are a group of Trans–New Guinea families in central New Guinea established by Timothy Usher, though with precedents in earlier studies.

Languages

The three language families in Awyu–Ok are as follows:

• Digul River (Greater Awyu)
• Kamula–Elevala
• Ok

The Oksapmin language is sometimes classified as the nearest relative of Ok. However, it's unclear whether the similarities are due to relationship or to contact between Oksapmin and Mountain Ok (or both).

Usher (2020) reconstructs the consonant inventory as follows:

*m	*n
*p	*t	*s	*k	*kʷ
*mb	*nd	*ndz	*ŋg	*ŋgʷ
	*s
*w	*ɾ	*j

Pronouns

Usher (2020) reconstructs the pronouns as:

	sg	pl
1excl	*ne	*nu
1incl		*nup
2m	*ŋgep	*ŋgip

The third-person pronouns are an innovation shared with the neighboring branch of Trans–New Guinea, Anim. The Awyu–Ok second-person pronouns show the same vowel ablaut for gender as well.
